The Usual Suspects

When Redfoot flicks his cigarette into the face of McManus, it was originally intended to hit his chest, so McManus' reaction is actually Stephen Baldwin's real unscripted reaction that Bryan Singer decided to keep in the movie.

Benicio Del Toro's delivery of the line "He'll flip ya'. Flip ya' for real" is straight from the movie _Thelonious Monk: Straight, No Chaser (1989)_ about jazz pianist Thelonious Monk. Monk says the line himself.

The role of Dave Kujan was offered to Robert De Niro and Christopher Walken, who both turned it down.

Michael Biehn turned down the role of McManus because of his previous commitment to filming Jade (1995)

Over a decade later, Kevin Spacey and Bryan Singer would reunite to work on the film Superman Returns, in which Singer cast Spacey as the diabolical super-villain Lex Luthor.

The Usual Suspects was the second movie where Peter Greene refers to someone else as "The Gimp", the first being Pulp Fiction ("Bring out the gimp"), referring to Kint as "the gimp" in this movie.

The fingers on 'Kevin Spacey (I)' 's left hand were glued together to make his character's disability more realistic.

In one scene, Hockney says in response to Fenster, "What did he just say?" That was Kevin Pollak the actor speaking, not his character; he actually did not understand what Benicio Del Toro said.

Throughout the movie, 'fuck' and its derivatives are used 98 times
