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.
