Bladerunner: cinematography, lighting, sets and locations

Cinematography for Blade Runner
by Herb A. Lightman and Richard Patterson

Jordan Cronenweth, ASC's photography for Blade Runner, with its use of strong shafts of light and backlighting, immediately evokes images from classic black-and-white movies, and it is not accident that it does. Cronenweth explains, "[Director] Ridley Scott felt that the style of the photography in Citizen Kane most closely approached the look he wanted for Blade Runner. This included, among other things, high contrast, unusual camera angles, and the use of shafts of light."

David Dryer, one of the special photographic effects supervisors, worked with black-and-white prints of most scenes in the film for one reason or another, and almost wishes the film could be released in black-and-white. He thinks it seems to have even more depth and style in black-and-white. Needless to say, this would not do justice to Cronenweth's work, but it is an indication of the way in which the photographic style of the picture harks back to classic movies.

Like every other aspect of the film, Cronenweth's photography takes the classic conventions one step further, and not the least of his tools in doing this is the use of color, or even the absence of color where it might normally be expected. "We used contrast, backlight, smoke, rain and lightning to give the film its personality and moods," the cameraman says. "The streets were depicted as terribly overcrowded, giving the audience a future time-frame to relate to. We had street scenes just packed with people. . . like ants. So we made them appear like ants — all the same. They were all the same in the sense that they were all part of the flow. It was like going in circlesÉ like going nowhere. Photographically, we kept them rather colorless."

If the people on the streets were colorless, the Los Angeles Street set was anything but: "The character and consequently the lighting of the street was achieved through the use of dozens of neon signs. We rented a number of them from One From the Heart. In order to achieve a photographic reality, the on-camera neons were often on dimmers set at a level just above where they would start to flicker. At the same time, the off-camera neons were used as the primary source of light whenever possible by leaving them at their brightest level. When the existing neons weren't sufficient for either illumination or dressing, we would create new ones on the spot and place them wherever we wanted. An example of this was placing letters on the side and strips along the interior of a bus that Deckard [Harrison Ford] runs through in one scene. At one point, we had a seven-man crew doing nothing but overseeing the neon signs. There were many more neons than there were dimmers, so we had to rob Peter to pay Paul at various times."

Cronenweth would supplement the neons on occasion: "What we needed was some accent lighting to make the range stand out, to glisten the street if necessary and to highlight objects or people. Lighting the set was a simple matter of using backlight in conjunction with the ambient light."


However, the neon lights were bright enough to enable Cronenweth to do some high-speed photography: "In the sequence in which Deckard is chasing a replicant named Zhora, the 'Snake Lady' (Joanna Cassidy), the script calls for her to run through a series of plate glass windows. The art director built a storefront situation appropriate for the action, but when it came to dressing it, Ridley was very unhappy with the first attempt. They tore all the dressing out and a week later presented a new interpretation, but he still hated it. Ridley himself finally had the wonderful idea of taking the neon signs off the street set and placing them in the windows of the stores. What developed was something that really worked. We then photographed the chase with multiple cameras running at various frame rates — normal and above normal. This created a pulsating effect in the neon which doesn't occur when photographing at normal camera speeds, but definitely does when shooting at higher frame rates. We lived with it by using the pulsing as an element of the chase."

Another example of the striking use of colored light is the scene in Sebastian's toy room, during which Deckard encounters another replicant, Pris (Daryl Hannah). She is made up with white makeup, and the scene is lit with rose-colored light.

Colored lights were also occasionally used to create a special effect for the replicant's eyes: "One of the identifying characteristics of replicants is a strange glowing quality in their eyes," Cronenweth notes. "To achieve this effect, we'd use a two-way mirror — 50 percent transmission, 50 percent reflection — placed in front of the lens at a 45-degree angle. Then we'd project a light into the mirror so that it would be reflected into the eyes of the subject along the optical axis of the lens. We'd sometimes use very subtle gels to add color to the eyes. Often, we'd photograph a scene with and without this effect, so Ridley would have the option of when he'd use it."

In discussing the photography of Blade Runner, however, Cronenweth emphasizes that technique was not the most important consideration. "The thing that was unique was not the equipment or the gels or the intensity or the hard or soft light," he stresses. "It was the concept behind each situation telling the story. Since the film is set in the future, unusual sources of light could be used where one would not accept them in a contemporary setting. For example, many of the people on the street set carried umbrellas that had fluorescent tubes incorporated in their shafts, providing a light source which could create a glow on their faces."

Cronenweth is particularly emphatic about backlight and contrast. "I can never use enough backlighting," he says. "It's just that some directors want to see the actors' faces. I keep telling them that the audience only goes to see the sex." The cinematographer is as interested in creating mood or an effect as he is in lighting an actor's face. He tends to use soft frontlight with a hard backlight, although, he adds, "I love hard light in the face if it is overexposed. I think that's beautiful. It's different; it's unusual. It's exciting; it's violent.

"Blade Runner is a piece that calls for extremes. It's naturally a wonderful vehicle for this kind of lighting. It's theatrical, but it will be very real in the film. In this film, I think you'll just accept it. It transcends theatricality."

In addition to using soft frontlight, Cronenweth often lit faces from below. In addition to the glowing umbrella handles, he often made use of water or other reflective surfaces to provide uplight in several scenes. The combination of warm soft uplight in the foreground with hard backlight and smoke in the background is probably the most characteristic feature of the lighting style for Blade Runner.
The other key ingredient in the photography of Blade Runner is the use of shafts of light. "That was an idea that both Ridley and I happened upon independently and had talked about," Cronenweth reveals. "We shared that concept, and it became one of the major themes of the film photographically. We used it over and over again in different applications. One way we justified their constant presence was to invent airships floating through the night with enormously powerful beams emerging from their undersides. In the futuristic environment, they bathe the city in constantly swinging lights. They were supposedly used for both advertising and crime control, much the way a prison is monitored by moving search lights. The shafts of light represent the invasion of privacy by a supervising force; a form of control. You are never sure who it is, but even in the darkened seclusion of your home, unless you pull your shades down, you are going to be disturbed at one time or another.

"After many tests with various units, gaffer Dick Hart came up with the most effective light to do the job, a Xenon spotlight commonly used for night advertising at sports events. This concept gave us some wonderful opportunities. For example, there's a late-night scene in Deckard's apartment kitchen which was played with the lights out. He has just had a hell of a struggle with one of the replicants. Having barely survived, he is now standing near the refrigerator. Rachel [Sean Young] is standing by the sink, which has a window above it. She is illuminated by a soft backlight through the window and the last traces of light filtering across the room from the refrigerator. Occasionally, one of those strong beams of light cuts through the sink window and glows the room just enough to read her face.
"Naturally," Cronenweth continues, "to create shafts of light, one must have some medium, which necessitated the use of smoke. The story lent itself very well to it, in the context of a highly polluted environment. It was very interesting to work with this constant atmosphere. Smoke is wonderful photographically, but not without its problems. It's hard to control, mainly due to drafts, and a lot of people find it objectionable to work in. Beyond this, it's important to keep the smoke level density constant, as a very subtle change in this density can result in dramatic changes in contrast. The only practical way to judge smoke density is by eye."

He jokingly adds, "I find that a good density is achieved just before I lose consciousness."
Cronenweth wanted to maintain the same texture even in situations where smoke wasn't used as heavily, and accomplished this by using low-contrast filters. He details, "We changed filters in conjunction with the angle of light and density of smoke. The stronger the backlight, the lighter the filter."

The cameraman particularly enjoyed photographing Sean Young, the leading lady in Blade Runner. "Sean has a wonderful, light, creamy, highly-reflective skin, among other beautiful features," he attests. "She also wore her hair up for a good part of the picture, enabling me to light her neck with hard backlight while lighting her face with soft frontlight. My favorite close-up in the film is the shot on her while Deckard is giving Rachel the Voigt-Kampff test. [See Best-Shot Films 1950-1997 #9 Blade Runner] She is holding a cigarette in her right hand, and the key light was at such an angle so as to strike only her hair, neck and hand and the smoke of the cigarette."

All of the sets for Blade Runner had ceilings in them, and some were built very low to enhance the feeling of containment, a motif particularly well-suited to the anamorphic format. "We had to light from the floor or through the windows," Cronenweth describes. "There is a lot of night photography lit through windows. The sources would vary. They could be anything including searchlights, signs, direct light, indirect light, colored light, or lightning. In Deckard's apartment, we created zones of light that automatically illuminated when one walked in — an energy-saving device of the future perhaps. As the depths of the apartment were penetrated, more lights went on until finally the entire place was lit. This effect was mostly lost, however, in the final cut of the film."

Perhaps the most interesting set was replicant creator Dr. Tyrell's cavernous office. According to Cronenweth, "This was one of the most exciting to work in. It was very large — approximately 60' long by 30' wide — with three huge windows along one side and structural ceilings supports rising from a shiny black marble floor. The walls were gray cement and the room was virtually colorless.
"The scene called for the room to be illuminated by sunrise. Outside the windows, we had a front-projection screen upon which was projected an 8" by 10" plate of the futuristic city at sunrise, which [special photographic effects supervisor] Doug Trumbull had created. This enabled us to photograph the players walking in front of the lower part of the screen, and gave Doug the opportunity to create a background with movement in it for the upper portions of the screen area. We had to coordinate the color of the set to match the color of Doug's sunrise. Sunlight was created through the use of arcs outside the windows and amber gels.

"At a certain point in the scene, in order to reduce the light level in the room for Rachel's Voigt-Kampff test, Tyrell [Joe Turkel] presses a button to cause enormous tinted shades to descend over the windows. The 'shades' were actually put in later optically; however, the lighting effect of the shades being lowered had to be created while photographing the scene. To accomplish this, Carey Griffith, the key grip, built a rig that would allow a very large .6 neutral density filter to slide down over the six arcs being used to simulate sunlight."
The set for Tyrell's office was also redressed to serve as two other spaces: Tyrell's bedroom, which was photographed in flickering firelight, and the Tyrell Corporation interview room, which was photographed with bright white shafts of daylight. According to Cronenweth, "That set looks totally different in each situation, and yet it's the same set. The flickering for the firelight was created by arcs shooting through torn strips of silk for transmission and torn strips of Duvateen for shadows."



The most unusual set for the film was the "Ice Room," which was built in a meat storage locker in order to create the effect of a refrigerated genetic-engineering laboratory. The ceilings were repeatedly hosed down over five days to form icicles, and then the crew shot for two days at minus 7°F while it was 98°F outside. Cronenweth started out using arcs to light the set, but soon discovered that they were using more oxygen than was coming into the room, except when the door was open. This necessitated changing to HMIs. The set was translucent along one side, allowing Cronenweth to light the scene through the wall. He added smoke to the scene to compliment the effect of cold breath.

Another interesting photographic problem on Blade Runner was shooting the interiors of a flying police car — a "Spinner" — in order to create the illusion of movement. The Spinner was capable of moving in any direction and traveling at very high speeds. Cronenweth explains his approach: "In order to create a sense of the vehicle traveling at night, we used several techniques. We built two sets of programmable strip lights, each about 8' long and each containing 12 Photofloods wired individually and dyed different colors. We placed them on the exterior of each side of the Spinner cockpit. The bulbs were then flashed at assorted intervals in conjunction with each other and individually. Additional movement was created with set lights activated by keyboard, so the lights were literally 'played.' Moving the camera on both axes by using double gear heads, and using wind, water and smoke enhanced the illusion. To create additional movement for day scenes, we'd use clear globes in the strip lights and a moving arc mounted on a Chapman crane to simulate a change in the Spinner's position relative to the sun."

Although most of the picture was shot on a stage, some notable Los Angeles landmarks were used as locations. The exterior of Deckard's apartment was Frank Lloyd Wright's Ennis-Brown house, designed in 1924 using a Mayan block motif. The Bradbury Building, designed by George Wyman in 1893, was used for the violent final showdown between Deckard and replicant leader Roy Batty (Rutger Hauer), as well as for a scene in which Sebastian (William Sanderson) takes Pris to his apartment. The downtown Pan Am building was used for a scene in which Deckard and Gaff (Edward James Olmos) search a hotel room for clues.

However, one of the film's most striking "exteriors" was actually shot at the studio. "The rooftop sequence at the end of the picture was planned to be photographed on real rooftops in downtown Los Angeles," says Cronenweth. "It turned out to be impractical to do it there, however, because of the scope of the shots and the difficulty of achieving some of the effects. We decided to film the sequence on the Warner Bros. backlot. This required building a couple of moveable rooftop units approximately 30' high. In order to show extreme height, we worked very closely with photographic effects supervisiors Doug Trumbull, Richard Yuricich [ASC], and David Dryer in order to make certain key matte shots, using our rooftop sets as the foreground. Of course, whenever we did a matte shot, we'd use a 65mm camera.

"We had to do a lot of 65mm photography from very high parallels which couldn't move at all. This meant reinforcing the normal parallels with additional steel and weight. [Key grip] Carey Griffith made reservoirs in the bottom of the parallels and filled them with several hundred gallons of water. That, in conjunction with reinforced steel going up the sides of each parallel and the use of solid bracing, made a high, rigid camera platform. We spent over two weeks on top of the roofs, turning them from time to time to obtain new backgrounds. We also worked with rain, smoke, lightning and moving shafts of light in this sequence. However, none of these effects could be used when making matte shots because they disappear in the matte area while remaining in the live-action area. One would then be confronted with matching the matte area effects to the live action rain, smoke, etc. The procedure, therefore, when doing matte shots is to put these effects into the composite on an overall basis later."

BLADE RUNNER: THE CINEMATOGRAPHY OF JORDAN CRONENWETH

bladeRunner_350a
Last Friday, I did my second entry in a weekly feature I started on the work of cinematographers. That entry covered Jeff Cronenweth, who is known for his work with David Fincher in films like The Social Network, Fight Club, and The Girl with the Dragon Tattoo. I wanted to write a follow-up to that today, because I think it’s called for in this case. Jeff Cronenweth is the son of the late Jordan Cronenweth, and he learned quite a bit from his father. This article will go over one film by him that ultimately, along with his son, became one of his life’s most impactful legacies: Blade Runner.
This is a film that I consider to be in my all-time favorites list. Its cinematography is now considered a milestone in the progression of film, winning awards from the British Society of Cinematographers, the Los Angeles Film Critics Association, and BAFTA. In 1993, Blade Runner was even chosen for preservation in the United States National Film Registry by the Library of Congress. It’s needless as well to say that this film’s cinematography influenced not only science fiction films, but movies of all genres up to today.
That’s because Blade Runner isn’t just a science fiction film. It’s not a Star Wars by any stretch of the imagination at all. Blade Runner was a noir; and just as the film took its cues from classic noir narratives in Hollywood cinema, so did the ways in how it was filmed.
Director Ridley Scott wanted the film to mimic the cinematography of the 1937 classic Citizen Kane. So when you watch Blade Runner, you’ll notice how it utilizes strong backlighting and light shafts. That’s something black-and-white cinematography is well recognized for, and that’s something intentionally brought over to this film by Jeff Cronenweth and implemented into color.
“We used contrast, backlight, smoke, rain and lightning to give the film its personality and moods. The streets were depicted as terribly overcrowded, giving the audience a future time-frame to relate to. We had street scenes just packed with people. . . like ants. So we made them appear like ants — all the same. They were all the same in the sense that they were all part of the flow. It was like going in circles- like going nowhere. Photographically, we kept them rather colorless.” – Jordan Cronenweth (ASC, Mar 1999)
You’ll see the backlighting come up quite a bit in the film.

Or you can take a look at some of the facial contrast that Cronenweth implemented. You’ll notice how hard both hit.
bladeRunner_050i

If you’ve read about Digital Bolex’s newly announced D16M, you’ll remember the advantages that were given for black and white sensors: the strong presence of texture, contrasting, and light, with little detail being sacrificed at all in low light. This is one of the biggest highlights of black-and-white cinema in general, and considering it was all Hollywood used up until around the 1960s, it’s a medium that’s still going strong in popularity today because of its timeless style. David Dryer, a photographic effects supervisor for Blade Runner, even stated once of how he almost wishes the film could be released in black and white.
When you examine it closely, you’ll realize that pretty much all of it was filmed to mimic a classic manner; it didn’t just stop at black-and-white. In other words: I’ve always considered Blade Runner to be a noir before a science fiction film. To me it’s The Maltese Falcon with a Ghost in the Shell-style future set as its background. With how well the film achieved its goals of emulating classic noir imagery, it made me completely forget that it was set in the future in the first place.
But that future.
bladeRunner_045c
bladeRunner_073a
That future was envisioned through painstaking set development. Along with the goal of maintaining classic elements within the film itself came the goal of creating a futuristic city that audiences could believe in. Naturally, the set designs for a post-modern film like this called for a heavy use of neon lights- lights like the ones in nighttime Tokyo, except amped up to achieve the cyberpunk look that Blade Runner ultimately helped inspire. One of the most important and prevalent tools used in the photography by Jordan was the use of shaft lighting. Smoke was used as the medium that light was shown off with. And that smoke was perfect for the setting of this film: this future was polluted, ghetto, urban, and ridden with crime.

Future Los Angeles. The neon lights, the thick fogs, the orange fire-fueled police vehicles flying in line with air traffic, the Coca-Cola advertisements glowing off of buildings with lit projections for walls- the setting of this film served as a direct contrast to the classic noir feel that was ultimately its heart and soul. Blade Runner is a timeless story beating within the exoskeleton of a setting beyond time itself. And it’s because of the visions of people like Jordan Cronenweth that a film like that could come to fruition that beautifully.

Bladerunner production and design
























That Ridley Scott‘s “Blade Runner” had a troubled production is no secret, with currently four different versions of the movie — 1982 Theatrical Version, 1982 International Version, 1992 Director’s Cut and 2007 Final Cut — all readily available for those who truly want to dip into the tweaks and changes made along the way. However, uncovered notes from a pre-screening of the film for producers perhaps offer the most entertaining insight into what the filmmaker was up against in making the movie.
The comments from three Tandem Productions executives after a January 1982 (or handwritten as “1982!”) screening is illuminating. This appears to be the screening of the workprint (also available in the special edition sets of the movie) given the noted absence of Vangelis‘ score. Among their 21 comments are such pieces of constructive criticism as: “Voice over is an insult,” “This movie gets worse every screening,” and “Were they all on drugs when they did this?” In case you’re wondering who said what, “J.P.” is Jerry Perenchio (who hasn’t done much since), “B.Y.” is Bud Yorkin, and “R.F.” is Robin French. On a lighter note – if you want to relive the “Blade Runner” magic but don’t have time to watch the whole film, here is a pretty awesome vintage promo reel. [via io9]

Bladerunner as film noir


A GUIDE TO FILM NOIR GENRE

by Roger Ebert January 30, 1995


1. A French term meaning "black film," or film of the night, inspired by the Series Noir, a line of cheap paperbacks that translated hard-boiled American crime authors and found a popular audience in France.Film noir is . . .

2. A movie which at no time misleads you into thinking there is going to be a happy ending.

3. Locations that reek of the night, of shadows, of alleys, of the back doors of fancy places, of apartment buildings with a high turnover rate, of taxi drivers and bartenders who have seen it all.

4. Cigarettes. Everybody in film noir is always smoking, as if to say, "On top of everything else, I've been assigned to get through three packs today." The best smoking movie of all time is "Out of the Past," in which Robert Mitchum and Kirk Douglas smoke furiously at each other. At one point, Mitchum enters a room, Douglas extends a pack and says, "Cigarette?" and Mitchum, holding up his hand, says, "Smoking."

5. Women who would just as soon kill you as love you, and vice versa.

6. For women: low necklines, floppy hats, mascara, lipstick, dressing rooms, boudoirs, calling the doorman by his first name, high heels, red dresses, elbowlength gloves, mixing drinks, having gangsters as boyfriends, having soft spots for alcoholic private eyes, wanting a lot of someone else's women, sprawling dead on the floor with every limb meticulously arranged and every hair in place.

7. For men: fedoras, suits and ties, shabby residential hotels with a neon sign blinking through the window, buying yourself a drink out of the office bottle, cars with running boards, all-night diners, protecting kids who shouldn't be playing with the big guys, being on first-name terms with homicide cops, knowing a lot of people whose descriptions end in "ies," such as bookies, newsies, junkies, alkys, jockeys and cabbies.

8. Movies either shot in black and white, or feeling like they were.

9. Relationships in which love is only the final flop card in the poker game of death.

10. The most American film genre, because no society could have created a world so filled with doom, fate, fear and betrayal, unless it were essentially naive and optimistic.

Blade Runner as Film Noir / Neo-Noir

Blade Runner as Film Noir
The term film noir literally means ‘black film’. It is debatable whether film noir is a proper genre. It may be more appropriately identified as a certain ‘style’, one with a consistent set of visual and thematic codes, which can be used in films with differing genre, settings and characters. But that is mostly academic, and for our purposes here it does not really matter. It is important to note that strictly speaking Blade Runner is not a film noir, but was influenced by the film noir styles of the 1940s and 1950s. It would more appropriately fall into the category of ‘neo-noir’, which are basically noir influenced films made from 1960 onwards. But seeing as neo-noir is of course dependant on film noir, let us consider some of the characteristics of film noir and then tie them in with Blade Runner.
Attempting to define film noir
There are some useful extracts from the book The Philosophy of Film Noir (2006), edited by Mark T. Conard. As its title suggests, this book deals very much with the deeper philosophical aspects of film noir, and some of these will be looked at in relation to Blade Runner in the themes/philosophy section. But there are also some definitions as to what film noir is all about:
“The claustrophobic settings are awash in deep shadows, the streets are rain swept, it always seems to be night, and the atmosphere is charged and angst ridden. We know the stories; we love the noir style, at once romantic and pessimistic; we sympathize, maybe even identify, with the doomed antihero; the anxiety and sense of alienation are uncomfortably familiar…” (p.1)
This is already starting to feel a lot like Blade Runner…let’s go on:
“Critics tend to identify the classic noir period as falling between 1941 and 1958, beginning with John Huston’s The Maltese Falcon and ending with Orson Welles’s Touch of Evil, two masterpieces of noir. This period, not coincidentally, lasts from America’s involvement in World War II through the postwar era. We can easily identify classic film noir by the constant opposition of light and shadow, its oblique camera angles, and its disruptive compositional balance of frames and scenes, the way characters are placed in awkward and unconventional positions within a particular shot, for example. But, besides these technical cinematic characteristics, there are a number of themes that characterize film noir, such as the inversion of traditional values and the corresponding moral ambivalence (e.g., the protagonist of the story, who traditionally is the good guy, in noir films often makes very questionable moral decisions); the feeling of alienation, paranoia, and cynicism; the presence of crime and violence; and the disorientation of the viewer, which is in large part accomplished by the filming techniques mentioned above…These classic noir films have their roots both in the hard-boiled literature of the thirties and forties (think here, e.g., of James M. Cain, Raymond Chandler, David Goodis, and Horace McCoy) and in the German/Austrian immigration during and after the war, given that a number of very important writers, directors, and other film technicians were German or Austrian émigrés.” (p.1-2)
That is a fairly comprehensive definition. How about the entry from the ever-popular Wikipedia? Here are some extracts:
“Film noir is a cinematic term used primarily to describe stylish Hollywood crime dramas, particularly those that emphasize cynical attitudes and sexual motivations. Hollywood’s classic film noir period is generally regarded as stretching from the early 1940s to the late 1950s. Film noir of this era is associated with a low-key black-and-white visual style that has roots in German Expressionist cinematography, while many of the prototypical stories and much of the attitude of classic noir derive from the hardboiled school of crime fiction that emerged in the United States during the Depression”
Further on in the article there is a section on ‘approaches to defining noir’:
Visual Style
“Film noirs tended to use low-key lighting schemes producing stark light/dark contrasts and dramatic shadow patterning. The shadows of Venetian blinds or banister rods, cast upon an actor, a wall, or an entire set, are an iconic visual in film noir and had already become a cliché well before the neo-noir era. Characters’ faces may be partially or wholly obscured by darkness—a relative rarity in conventional Hollywood moviemaking…
Film noir is also known for its use of Dutch angles, low-angle shots, and wide-angle lenses. Other devices of disorientation relatively common in film noir include shots of people reflected in one or more mirrors, shots through curved or frosted glass or other distorting objects (such as during the strangulation scene in Strangers on a Train), and special effects sequences of a sometimes bizarre nature. Night-for-night shooting, as opposed to the Hollywood norm of day-for-night, was often employed. From the mid-1940s forward, location shooting became increasingly frequent in noir.”

Typical example of noir shadows and the bar blind effect
Structure and Narrational Devices
“Film noirs tend to have unusually convoluted story lines, frequently involving flashbacks and other editing techniques that disrupt and sometimes obscure the narrative sequence. Framing the entire primary narrative as a flashback is also a standard device. Voiceover narration, sometimes used as a structuring device, came to be seen as a noir hallmark; while classic noir is generally associated with first-person narration (i.e., by the protagonist)…”
Plot, Characters, and Settings
“Crime, usually murder, is an element of almost all film noirs; in addition to standard-issue greed, jealousy is frequently the criminal motivation. A crime investigation—by a private eye, a police detective (sometimes acting alone), or a concerned amateur—is the most prevalent, but far from dominant, basic plot. In other common plots the protagonists are implicated in heists or con games, or in murderous conspiracies often involving adulterous affairs. False suspicions and accusations of crime are frequent plot elements, as are betrayals and double-crosses…
Film noirs tend to revolve around heroes who are more flawed and morally questionable than the norm, often fall guys of one sort or another. The characteristic protagonists of noir are described by many critics as “alienated”; in the words of Silver and Ward, “filled with existential bitterness”. Certain archetypal characters appear in many film noirs—hardboiled detectives, femme fatales, corrupt policemen, jealous husbands, intrepid claims adjusters, and down-and-out writers…
Film noir is often associated with an urban setting, and a few cities—Los Angeles, San Francisco, New York, and Chicago, in particular—are the location of many of the classic films. In the eyes of many critics, the city is presented in noir as a “labyrinth” or “maze”. Bars, lounges, nightclubs, and gambling dens are frequently the scene of action. The climaxes of a substantial number of film noirs take place in visually complex, often industrial settings, such as refineries, factories, trainyards, power plants…in the popular (and, frequently enough, critical) imagination, in noir it is always night and it always rains…”

Humphrey Bogart as the flawed private investigator Sam Spade roughing up shady businessman Joel Cairo in the 1941 classic 'The Maltese Falcon'
Worldview, morality, and tone
“Film noir is often described as essentially pessimistic. The noir stories that are regarded as most characteristic tell of people trapped in unwanted situations (which, in general, they did not cause but are responsible for exacerbating), striving against random, uncaring fate, and frequently doomed. The movies are seen as depicting a world that is inherently corrupt…
The tone of film noir is generally regarded as downbeat; some critics experience it as darker still—”overwhelmingly black”, according to Robert Ottoson. Influential critic (and filmmaker) Paul Schrader wrote in a seminal 1972 essay that “film noir is defined by tone”, a tone he seems to perceive as “hopeless”…definitive film noirs such as The Big Sleep, The Lady from Shanghai, and Double Indemnity itself are famed for their hardboiled repartee, often imbued with sexual innuendo and self-reflexive humor…”
And finally, here are some notes from filmsite.org:
“The primary moods of classic film noir were melancholy, alienation, bleakness, disillusionment, disenchantment, pessimism, ambiguity, moral corruption, evil, guilt, desperation and paranoia.
Heroes (or anti-heroes), corrupt characters and villains included down-and-out, conflicted hard-boiled detectives or private eyes, cops, gangsters, government agents, a lone wolf, socio-paths or killers, crooks, war veterans, politicians, petty criminals, murderers, or just plain Joes. These protagonists were often morally-ambiguous low-lifes from the dark and gloomy underworld of violent crime and corruption. Distinctively, they were cynical, tarnished, obsessive (sexual or otherwise), brooding, menacing, sinister, sardonic, disillusioned, frightened and insecure loners (usually men), struggling to survive – and in the end, ultimately losing.
Storylines were often elliptical, non-linear and twisting. Narratives were frequently complex, maze-like and convoluted, and typically told with foreboding background music, flashbacks (or a series of flashbacks), witty, razor-sharp and acerbic dialogue, and/or reflective and confessional, first-person voice-over narration. Amnesia suffered by the protagonist was a common plot device, as was the downfall of an innocent Everyman who fell victim to temptation or was framed. Revelations regarding the hero were made to explain/justify the hero’s own cynical perspective on life.
Film noir films (mostly shot in gloomy grays, blacks and whites) thematically showed the dark and inhumane side of human nature with cynicism and doomed love, and they emphasized the brutal, unhealthy, seamy, shadowy, dark and sadistic sides of the human experience. An oppressive atmosphere of menace, pessimism, anxiety, suspicion that anything can go wrong, dingy realism, futility, fatalism, defeat and entrapment were stylized characteristics of film noir. The protagonists in film noir were normally driven by their past or by human weakness to repeat former mistakes.
Film noir films were marked visually by expressionistic lighting, deep-focus or depth of field camera work, disorienting visual schemes, jarring editing or juxtaposition of elements, ominous shadows, skewed camera angles (usually vertical or diagonal rather than horizontal), circling cigarette smoke, existential sensibilities, and unbalanced or moody compositions. Settings were often interiors with low-key (or single-source) lighting, venetian-blinded windows and rooms, and dark, claustrophobic, gloomy appearances. Exteriors were often urban night scenes with deep shadows, wet asphalt, dark alleyways, rain-slicked or mean streets, flashing neon lights, and low key lighting. Story locations were often in murky and dark streets, dimly-lit and low-rent apartments and hotel rooms of big cities, or abandoned warehouses.”
Even after all the above ideas about what film noir is, the term is still tricky. There are critics who have identified film noirs that were released long before 1941, and many disagree that film noir ‘ended’ in 1958. But despite this, all the above definitions give us a pretty good idea of what film noir is about, even if it is still undecided whether it is a ‘real’ genre or not. From the above reading, it becomes pretty clear that Blade Runner fits into the film noir style.

Now let’s have a closer look at the film and some of the noir elements within it.
How is Blade Runner influenced by film noir?
By now it would have become fairly obvious how Blade Runner was influenced by film noir.
The film is set in an urban city, and it always seems to be night – it is always dark and raining. In a large number of scenes we see a strong contrast between deep shadows and brighter light. Often the faces of characters in close ups are half-obscured by shadow, with a strong white rim light around the edge of their head. Deckard is basically a hitman that is used as a tool by the police force, and he is clearly alienated and may have a questionable moral character. The whole society seems to be corrupted – status, power and wealth are still prevalent, prime examples being Taffey and Eldon. Crime and murder play prominent roles. Lastly, the overall tone of the film is cynical (apart from perhaps the ‘happy’ ending in the original cut).
Blade Runner as Neo-Noir
Neo-Noir is a term used to describe films that were made after the classic noir period (1941-58) and contain some of the themes and style of film noir. A large number of films fall into this category, with a consistent output of neo-noir films being released every decade from the 1960s to the 2000s.
Obviously Blade Runner deals with some issues that were probably not included in the film noir of the 1940s and 1950s. In this sense the film is ‘updated’, or more contemporary. These issues include globalisation, rapid technological and scientific advancement, mass media, and environmental degradation.
For this reason Blade Runner could perhaps more appropriately be defined as a ‘neo-noir’. Here are a few examples of other neo-noir films:

Chinatown: a 1974 classic starring Jack Nicholson

'Reservoir Dogs' is the 1992 debut film from director Quentin Tarantino

'Dark City' is a 1998 cult film

'The Usual Suspects', a 1995 crime/mystery film

The three matrix films are a popular example of neo-noir
There are countless other neo-noir films that have been released over the past few decades.
