Factual error: During the car chase at the beginning, they are chasing a car on Bigelow Blvd., less than a mile from downtown Pittsburgh and we see a big, brick hill they chase down. This hill is actually in Duquesne, PA more than ten miles south east of Pittsburgh. Then as you're watching they are still in the same area as Bigelow Blvd., in the Polish Hill section of Pittsburgh.
Revealing mistake: When Hardy goes to check out a victim with Christman, Christman gets in the water to flip the dead woman over and the dead girl blinks her eyes.
Continuity mistake: When Bruce and Sarah stop the drinking kids in the fast speed boat, they confiscate a bottle of scotch. BW opens the bottle to smell it, then the scene goes to the partner and back to him and he UNSCREWS the top and dumps the liquor over the side. He opens the bottle twice.
Revealing mistake: In the scene in the beginning where Jimmy is about to jump from the bridge, he is holding the cables holding the bridge up, which move and flex from his weight. Cables on suspension bridges are extremely tight from the weight and do not move at all if a person pulls them.Jacob La Cour
Revealing mistake: During the ending boat chase when Jimmy and Tom reach a small waterfall and go over it, their boats ramp up when they go off. There's no reason for them to do this other than stunt ramps put in place. And in several shots they go from nose up to nose down between shots. (01:33:01)Quantom X
Revealing mistake: The police car that gets turned over in the tunnel explodes just before impact by the pickup truck.
