Continuity mistake: The first scene with Murray Babitch driving across the George Washington Bridge from New York to New Jersey was actually filmed going the other direction. When driving from New York to New Jersey on the lower level of the bridge you enter a black tunnel first, and exit through a yellow tiled tunnel. The scene in the film starts in the yellow tiled tunnel - New Jersey to New York direction.
Continuity mistake: In the final shootout when Freddy is shot by Leo, he falls against the car parked in the driveway and dents the passenger door. When he gets up again after Gary shoots Leo, the dent is gone.
