* CelebrityVoiceActor: In the 1997 [[VideoGame/BladeRunner video game]], several characters are voiced by the actors who played them in the film.

** ''The Relentless Hunter'' (Venezuela)
** ''Imminent Danger'' (Portugal)
** ''Bounty Hunter'' (Romania)
** ''The Winged Bounty Hunter'' (Hungary)
** ''Silver Winged Bounty Hunter'' (China)
* {{Defictionalization}}:
** Deckard's whiskey glasses and bottle, trenchcoat and even the tiles in his apartment have been made into real (albeit [[CrackIsCheaper insanely expensive)]] products. Even the [[http://www.thinkgeek.com/homeoffice/gear/d163/ neon light umbrellas]] are available from Thinkgeek (albeit the Thinkgeek versions are. more practical LED/fiber-optic rather then neon tubes).
** The police offices constructed in Union Station, Los Angeles for the filming still stand till today, in use as station offices. The crew was able to get a little bit of a discount if Union Station officials agreed to keep the set for practical use after filming was over.
** Some cities, [[https://www.google.com/search?q=shanghai+looks+like+blade+runner particularly]] UsefulNotes/{{Shanghai}}, look more and more like ''Blade Runner'' every year.
* EnforcedMethodActing: The scene with Chew was shot in a freezer and was ice cold, so the cast really were shivering.
* ExecutiveMeddling: The ending in the original movie was changed by higher-ups due to its ambiguity, and narration was added to help dispel the ambiguity evident in most of the movie itself. The original ending has been restored and the narration deleted in the DirectorsCut.
* FlipFlopOfGod:
** Is Deckard a replicant? Director Creator/RidleyScott and lead actor Creator/HarrisonFord, as well as Rutger Hauer, screenwriters Hampton Fancher and David Peoples have all had contrasting views on the subject. Scott says yes; Ford, Hauer and the screenwriters say no. The novel on which the films based, ''Literature/DoAndroidsDreamOfElectricSheep'', has several strong hints that [[spoiler: he is in fact human.]]
** More solidified now in that it's generally agreed upon that Deckard is human in the theatrical cut and a replicant in the directors.
* TheProductionCurse: ''Blade Runner'' provides something of a variation on the theme: it suffered a similar curse, but instead of cast and crew members, it was the sponsors that got hit.
* PropRecycling:
** The spinners' dashboard displays are taken from ''Film/{{Alien}}''. Creator/RidleyScott directed both films, so this may actually be a ShoutOut.
** The very top of the roof of the police headquarters building was originally the ceiling of the Mothership interior from ''Film/CloseEncountersOfTheThirdKind''. The building itself is rather similar to the Tower of Babel as depicted in {{Film/Metropolis}}
** One of the buildings next door to the police station is a model of the [[Franchise/StarWars Millennium Falcon]] tilted vertically and covered with Christmas lights.
** The ''Film/DarkStar'' miniature can be seen in the background near the police station as well.
** Additionally, later sci-fi films would sometimes recycle props and set pieces from this one. Be on the lookout for a spinner in the junkyard in ''Film/{{Soldier}}'', and check out Craig Bierko's apartment in ''Film/TheThirteenthFloor''.
** Some of the Lord of Darkness' palace interiors from ''Film/{{Legend 1985}}'' (most notably, the huge, spiraling columns) were featured in this film.
* ScienceMarchesOn: Tyrell's explanation to Roy for why the DNA of a mature replicant can't be altered effectively doesn't stand up to modern understanding of genetics. Then again, this might be intentional, as the script hints that Tyrell may be lying about there being no possibility of lifting the lifespan limitation.
* ThrowItIn:
** There are a few ad-libbed lines, most notably in the FinalWords of both Leon and Roy Batty.
** Daryl Hannah really slipped and smashed her elbow throough a car window, chipping it in eight places.
*** In Dangerous Days, she shows us the scars.
* TroubledProduction: For a film now considered a sci-fi classic, its creation was a difficult process:
** The original screenwriter, Hampton Fancher, was eventually distanced from his script for being too protective, and David Peoples created the script that eventually was filmed.
** A critical financier went bankrupt at the eleventh hour, leading to some desperate deals shortly before production began.
** Harrison Ford often went between impatient and bored during production.
** Sean Young was cast by Scott for her Ava Gardner-esque looks, although many preferred another actress, Nina Axelrod. Young was unknown and also inexperienced, which seemed at times to annoy Harrison Ford.
** Scott made comments during the shoot that he preferred working with UK crews (as he did with ''Alien'') which annoyed the mostly American crew.
** Scott, coming from advertising and by his own admittance very controlling over visuals, made Art Director David Snyder's position practically moot.
** The Director of Photography, Jordan Cronenwith, suffered from Parkinson's disease and during the shoot was very weak and worked in a great deal of pain; By the final month of shooting, he was working from a wheelchair.
** Scott took multiple takes for seemingly innocuous scenes, leading one to wonder if he was really looking for the right look, or just infuriating his producers.
** Test screenings were sharply divided over the tone of the film. The producers themselves called the voiceovers 'dull', and Ford himself was not a fan of them. Ford cops later to trying to make them dull in the hopes they were removed. In the initial theatrical release, they stayed in (but were removed in the Director's and Final Cuts of the film.)
* WhatCouldHaveBeen:
** In the early 1970s, a relatively unknown young director named ''Creator/MartinScorsese'' was in line to direct the film.
** This was offered to Creator/RalphBakshi. He passed on it, but recommended Ridley Scott for the director's chair. And the rest is history...
** DustinHoffman was originally cast as Deckard. Scott intended to subvert the typical image of the burly HardboiledDetective, and Hoffman would fit that well. This period of the film's pre-production got so far that even some of the early storyboards featured Hoffman's likeness on images of Deckard.
** An earlier draft of the script, called "Dangerous Days" would have been a far more action-packed affair, including a famous unused introduction of Deckard, where he shot a seemingly innocuous man, then took his skull apart to reveal mechanical components.
** Creator/RobertMitchum was reportedly considered for the role of Deckard at one point as a shout out to his own background in film noir thrillers, but declined the role - which is just as well as he would have been too old for the part anyway.
* WordOfSaintPaul: Creator/HarrisonFord has stated that he believed Deckard to not be a replicant, as being one would undercut the theme of his character rediscovering his own humanity, and turns the man vs. machine climactic battle into a robot vs. robot fight. Creator/RidleyScott on the other hand, claims that Deckard was always meant to be a replicant. After the DirectorsCut, Scott insists that Ford changed his stance and now says Deckard is a Replicant, but he has yet to say it himself.
