Trivia: The big speech from "Couldn't you find anyone worse? A child molester..." to the bit where Stu is shot was filmed in one take. Colin Farrel did everything and surprised himself and the crew. When he hit the floor, the crew (and the extras) had to contain their applause until the cameras stopped rolling.
Trivia: When The Caller tells Stu that "you can be shot 41 times for just pulling out your wallet," he is referring to Amadou Diallo, an innocent West African immigrant who was shot to death in his apartment room in 1999 when undercover New York City police detectives fired 41 shots at him after he pulled out his wallet. They thought he was pulling out a gun. Before the time of the shooting, Diallo, was suspected to be a serial rapist which he was not. (00:32:25)
Trivia: The extras had no idea what was going to happen each day (the film was shot in sequence) so their reactions are totally real.
