Trivia: At the beginning when the coffin is opened, the clock strikes 13 times.
Trivia: During the big chase scene Marilyn Burns was running so slowly that Gunnar Hansen stopped to cut tree branches so he wouldn't outrun her.
Trivia: Stars Paul Newman and Steve McQueen apparently argued intensely over who should get top billing. In the end the producers settled for a compromise: reading the film poster (which is reproduced as the DVD cover) top to bottom, Paul Newman is first, i.e. higher, or "top" billing. But reading left to right, Steve McQueen is first. The same applies to their photographs either side of the main artwork, McQueen on the left but Newman (marginally) higher up. Ironically, this billing format was an issue when McQueen was considered for a role in "Butch Cassidy and the Sundance Kid."
Trivia: The man who plays that young deputy who bullies Warren Beatty in a bar (they also get into a rough car-chase later in the film) is Earl Hindman, whose most famous role came with the popular (here in Finland also) 1990's series "Home Improvement". He was that "faceless" neighbour of Tim "The Tool Man" Taylor's.
Trivia: The dream sequence in which Harry tries to talk to Ann was originally meant to take place in real life (within the film, that is). The production didn't have time to finish the scene and the fog effects looked too phony. But rather than scrap the scene entirely, editor Walter Murch came up with the idea to include the footage as a dream.
