From The Quentin Tarantino Archives
- A 1981 conspiracy thriller written and directed by Brian DePalma. Starring: John Travolta (Jack), Nancy Allen (Sally), John Lithgow (Burke), Dennis Franz (Manny Carp). Original Score by Pino Donaggio.
- Tagline: Murder has a sound all its own.
- During the editing process, two reels of footage from the Liberty Parade sequence were stolen and were never to be seen again. This meant that the scenes had to be reshot at a cost of $750,000. Cinematographer Vilmos Zsigmond was no longer available, so he was replaced by Laszlo Kovacs.
- The idea of a man discovering a crime by listening to a recording is a reinterpretation of Michelangelo Antonioni's film Blowup (1966), but using sound instead of photographs. The same idea was used by Francis F. Coppola in The Conversation
- The accident at the start of the film alludes to the Kennedy incident at Chappaquiddick.
- Also alludes to the Watergate scandal and the JFK assassination.
- John Travolta suffered from insomnia during the shoot. His lack of sleep helped him create a very moody performance and is why his character seems so downtrodden throughout the movie.
- In the French version, John Travolta's voice was dubbed by Gérard Depardieu.
