Revealing mistake: Near the beginning of the film, when Charlie and Brian steal the Honda there is a shot where Brian says "Charlie, slow down, think". By comparing the view outside of the car window in this shot to the surroundings of the previous and subsequent shots, we can see that it was filmed out of sequence, and in a different part of the parking lot.
Revealing mistake: While running away from Morley and Abbott and the Triads, there is a shot where Charlie and Brian take cover behind a red car. This single shot is the amalgamation of two different shots because the camera suddenly jerks to the side, as seen by the position of the "Priority Avenue" sign in the background.
Revealing mistake: During the robbery of the Triads, Charlie and Brian put a bomb in Abbott and Morley's car. In the shot of the car blowing up, the car is parallel to a brick wall. However, there was no brick wall near the car when Abbott and Morley parked it.
