Continuity mistake: When Rooker has his gun pointed at Westlake during the climax, watch closely. Throughout the scene, he's holding his gun sideways in a side grip. Right after he says the line "I don't think you'll be needing that anymore, doc!", he rotates the gun upright into a normal grip. However, in the very next shot, he's once again holding his gun in a sideways in a side grip. (These shots are back-to-back, so there's no way he was able to rotate it again between cuts).
