Continuity mistake: When the story begins, and the police car made its run towards the first crime scene, the aerial shot of the car doesn't match with the tail lights, we see it's an older car vs a newer car.
Factual error: The movie is set in Philadelphia, but the bus at the beginning crashes at a crossroad in front of the fast food joint Admiral Submarine, a recognizable location in Brantford, Ontario, where the movie was shot. (00:05:00)
