Factual error: When Trevor is struck by the VW Beetle, not only is he not thrown forward along the Beetle's path, he actually lands well behind the point of impact - more than half the length of the parked van. He doesn't bounce off another object that changes his direction. He's just thrown up, then falls rearward above the car. (01:08:35)johnrosa
Revealing mistake: After Trevor is hit by the VW Bug, the arm he lands on disappears partially into the street, making the CGI obvious.
Trivia: Christian Bale dropped approximately 60 pounds for the role, going from 180 to 120, by eating a diet of one can of tuna and an apple a day for months. This is the most weight ever lost by an actor for a film role. Within 6 months of this film he then put on 100 pounds to play Batman in Batman Begins.
