Factual error: One of the main characters has a Harley Davidson. The movie is supposed to take place in the fifties. The Harley had an electric start primary cover which wasn't made by Harley until 1965.
Visible crew/equipment: While Frannie and Annie are in the jewelry store, the movement of filming equipment is visible beside Frannie, at the bottom right corner of the screen. It happens again later, when Stanley is also at the jewelry store with them, and this time the film equipment is beside Annie and then Stanley. (00:27:40 - 00:59:15)
Continuity mistake: When Chico phones Jane for a date, it cuts to both of them riding on the motorcycle. In these shots, Jane's hair is quite long and well past her shoulders, but when they arrive at Coney Island, Jane's hair is much shorter, not even reaching her shoulders. This happens again, when Chico picks up Jane at her house with the "borrowed" Packard, the back of Jane's hair is long, but when they get to the drive-in her hair is shorter. (00:18:25)
Continuity mistake: When the guys use the key to steal the car, its back license plate number is 4N-4290, but when Chico pulls into the drive-in, the front plate number is SV-5875. Then when Chico reverses the car, the front license plate number is 4N-4290. (00:42:40)
