Visible crew/equipment: During the scene where Seagal is locked in the room and creates his knife gun, Seagal walks over and smashes a wall. As the camera pans around from right to left, the camera goes past him and continues to the left showing a crew member facing him.
Continuity mistake: When Jack shoots the cop Urick, the slug perforates his suit coat, both front and back, as well as his right lung. However, when he rendezvous with the Russians atop the parking garage, his suit coat is pristine. Had he changed into another identical coat, would he have not changed his bloody shirt and tie at the same time?
