Requiem for a Dream/Trivia

• Creator Cameo: Hubert Selby Jr., the book's author, appears at the end as the abusive, laughing prison guard. And he filmed quite a bit more footage hurling verbal abuse at his own characters, which can be seen on the DVD.
• Executive Meddling: Released unrated, the studio forced Aronofsky to let them release an edited version to DVD to get Wal-Mart and Blockbuster to carry the film.
• Playing Against Type: Marlon Wayans (Tyrone) is best known for his comedic work.
• Throw It In: Harry's nurse, toward the end of the film, sticks out her tongue as she prepares the hypodermic shot. The director kept it.
• Tuckerization: Mr. Rabinowitz is named after the film's editor, Jay Rabinowitz.
