Deliberate mistake: In the last sprint towards the finish line, before they have to race on foot, the Lamborghini passes Fenderbaum and Blake. The red Ferrari they are supposed to be driving, is on the bed of a truck being towed. Notice the height difference between the two cars; about ten seconds later the two cars are pretty similar in height. (01:23:05)
The Cannonball Run (1981)
1 deliberate mistake - chronological order
Directed by: Hal Needham
Starring: Burt Reynolds, Dom DeLuise, Roger Moore, Dean Martin, Farrah Fawcett, Sammy Davis Jr.
Visible crew/equipment: A stock car carrying Mel Tillis and Terry Bradshaw drove into a hotel swimming pool. If you watch the car as it drives into the pool, you'll see the jump ramp built at the end of the pool.
Batman: Mad Dog, you are going to take the shortcut to the interstate, right?
Mad Dog: We're in this to win, ain't we? If you're gonna be a bear, be a grizzly!
Trivia: When Dom gets back in the airplane after getting beer, Burt is discussing cars with him to use in the race. He says they could use a black Trans-Am. Then he says that it's been done before. It has. Remember that movie called Smokey and the Bandit?
