• Defictionalization: Deckard's whiskey glasses and bottle, trenchcoat and even the tiles in his apartment have been made into real (albeit insanely expensive) products. Even the 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.
  • Enforced Method Acting: The scene with Chew was shot in a freezer and was ice cold, so the cast really were shivering.
  • Executive Meddling: 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 ending has -- thank God -- been restored and the narration deleted in the Directors Cut.
  • Flip-Flop of God: Is Deckard a replicant? Director Ridley Scott and lead actor Harrison Ford, as well as screenwriters Hampton Fancher and David Peoples, initially said no. Ever since the Directors Cut in 1993, they now say yes.
    • More solidified now in that it's generally agreed upon that he is human in the theatrical cut and a replicant in the directors
  • Hey, It's That Guy!:
    • Naturally, Dr. Jones is the protagonist.
    • Sheriff Dearborn is Sebastian.
    • Carinal Roark is Roy Batty.
    • Edward James Olmos in the role that made him famous (well, sort of) as Gaff. He only appears about three times, but he's got the best outfit in the movie and gets one of its last, and best, lines. If Deckard is a replicant himself, Gaff is presumably his human handler and the model for some of his fake memories.
    • Bryant is played by M. Emmett Walsh, who's been one of the ultimate 'That Guy's' over countless films, usually playing some sort of sleazy, amoral character.
  • Prop Recycling:
    • The spinners' dashboard displays are taken from Alien. Ridley Scott directed both films, so this may actually be a Shout-Out.
    • The roof of the police headquarters building was originally the ceiling of the Mothership interior from Close Encounters of the Third Kind.
    • One of the buildings next door to the police station is a model of the Millennium Falcon tilted vertically and covered with Christmas lights.
    • The Dark Star 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 Soldier, and check out Craig Bierko's apartment in The Thirteenth Floor.
    • Some of the Lord of Darkness' palace interiors from Legend (most notably, the huge, spiraling columns) were featured in this film.
  • Throw It In: Somehow "The tiny elevator whizzes down the huge nighttime pyramid" turned into stars zooming past the elevator cage on the screen. Since there is no way you would actually see this from an earthbound elevator, as anybody who has ever strolled down a hill at night intuitively understands, the result was to inject an unintentional Flash Back into the visuals at that point ... which luckily fit together with Roy's Final Speech a few minutes later.
    • Or, it's a view of the constant falling rain from Roy's perspective in the glass elevator...
  • Troubled Production: One of the most (in)famous in movie history.
  • What Could Have Been: This was offered to Ralph Bakshi. He passed on it, but recommended Ridley Scott for the director's chair. And the rest is history...
