Trivia: The film is primarily about cars and driving. Star Michael Caine could not drive at the time the movie was made. Charlie Croker is assumed to be driving when he picks up his Aston Martin at the garage but in the next shot, we see it arrive outside a hotel. Caine only gets out of the stationary Aston Martin. In other scenes, including the trip to Turin and the gold heist, Caine is a passenger. However, he is seen driving his E-type Jaguar into the Turin building where the Minis are being modified. The DVD confirms that Caine couldn't drive, but could just about manage the basics.
Trivia: The most famous line in this film is purely ad-libbed. Apparently a tough New York cabbie broke through and drove across one shoot, nearly running down Jon Voight (Joe Buck) and Dustin Hoffman (Enrico Salvatore "Ratso" Rizzo). Notice Voight's startled expression. Hoffman, still in character, slams on the hood and shouts at the cabbie, "Hey, I'm walkin' here. I'm walkin' here."
Trivia: During the Stuka attack on the radar station, the two Stuka radio controlled models that collide was a complete accident. It looked good so was left in the final version.
Trivia: Katherine Ross, (Etta Place) was caught operating a camera, filming some footage of the arrival of the train carrying the "super posse". In the late 60s the US film business was strict, closed shop union (to a great extent it still is) and Ross operating a camera was against every rule there is. Several senior crew members demanded her dismissal from the film but producer John Foreman and Unit Production Manager Lloyd Anderson, aware of the fact that a lot of scenes with her in it would have to be reshot at absurd expense, argued for a compromise to which the union agreed - none of the footage she shot would be used (it wasn't) and she would be asked not to be on set while scenes in which she was not involved were shot. Her gender was totally irrelevant to the issue. This is confirmed in William Goldman's excellent memoir, "Which Lie Did I Tell?"
