Continuity mistake: This is a mistake that goes on through the entire movie; mix-up with cars. There is, for example, a very special yellow sports car parked at the beach where the start of the race began. Later in the movie the two girls borrow this car from a mechanic, who is obviously not in the race, and would not have been at the beach. Even later the yellow car breaks down, and the two girls borrow a tow truck, leaving the yellow car behind. Some scenes later, there is a shot of a medley of cars coming down the road, and the yellow car is one of them. But how can this be, since the yellow car broke down a few scenes earlier? There is also a shot of Fenderbaum and Blake passing J.J. and Victor in their Dodge Daytona. The problem is that for the entire movie Fenderbaum and Blake was driving a Corvette, NOT a Daytona. The Daytona, however, is the car that Frank Sinatra uses for the last 10 minutes of the movie.
Visible crew/equipment: At the beginning of the film, a police car is chasing the black Mitsubishi. When the police car is gone, the Mitsubishi 'lands' on the roadside. Look at the shadow to see a portion of the crane that is lowering the car. It's the type used in junkyards that has a large magnet to lift cars.
Trivia: The man who got out of his Porsche at the starting line to chew out the driver of the monster truck (who later ran over the Porsche) was director Hal Needham.
