Trivia: All of the guards at the clinic on the mountain have the Olympic rings on their orange tracksuit tops.
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: 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: The filming in Czechoslovakia was interrupted due to life imitating art somewhat when in August 1968 the Soviets decided to invade. The evacuation of cast and crew was performed using a fleet of 20 taxis.
Trivia: Ernest Borgnine's limp is genuine because he broke his foot before production began.
