Continuity mistake: At the end of the chase between the Charger and the 'hot rod' police car, they speed into an intersection and turn left. Just before the police car is struck by a gray station wagon, the Charger can be seen leaving the road surface, headed into the trees and grass while braking hard (the stunt driver took the turn too fast and overshot it). The shot changes and the Charger is seen speeding away on the pavement without having had time to turn around, to get back on the road nor to return to high speed. (01:22:15)
Continuity mistake: In various scenes, an odd pattern of scratches appears and disappears from the top portion of the car's driver's-side door. These are due to the car's use as a 'camera platform' during some scenes (like filming Larry through his own window), and the camera mounts have made the scratches. It is obviously not collision damage. Because the camera isn't visible in these shots, this is a continuity error, not a visible equipment error. (01:25:15)
Continuity mistake: During the chase against the helicopter, some exterior shots of the Charger show all its windows are fully open, but all interior shots (and a few exteriors) show the rear side windows are closed. (01:25:15)
Continuity mistake: When we see the train from the front just before the collision at the end of the film, the staircase on its front/right corner is already heavily damaged/crushed. Then, as the car is about to collide with the train, we see the train in a side view and these stairs are perfectly fine. The approaching front view was obviously filmed after the crash. Note the same damage is on the train in the film's opening shot (just before the credits and theme song start). (01:30:55)
