Factual error: There is a shot with Wesley Snipes and Gary Busey aiming one another just to pull the triggers and discover that the guns are out of ammo. In fact, after the last shot (of the pistol, not the movie) the slide of a semi automatic pistol is retained open by the empty magazine, and doesn't return forward as we can see in the shot (of the movie, not the pistol). The reverse mistake is very common in movies, when the armorer loads just one round to be shot (in the movie as well as the gun) and the actor keeps fighting or menacing with an unloaded, breech opened gun.
Factual error: In the scene where the bad guy smashes through the window of the big building with Wesley Snipes, Snipes opens a parachute, his enemy falls straight, which is almost vertically, to the ground. In the next shot, the guy slams almost horizontally through the window of the truck.
