Factual error: When Jean-Claude is chased by the helicopter in the woods alongside the river, the man in the helicopter fires a MP5 machinegun, but it causes huge explosions, this is impossible, it's not a grenade launcher!
Continuity mistake: This scene is shown in the director's cut of the movie. When Van Damme rides the motorcycle and stands up on it you can clearly see the training wheels on the bike as he jumps over the van.
Continuity mistake: As Van Damme's character snaps the guy's arm in front of the broken window, we see him flip him round and the guy falls on the floor knocking over the chair directly in front of the window. Then as Van Damme walks over to give the lady her purse we see that the chair is now standing back up.
Continuity mistake: As Van Damme's character kicks the guy through the window in the first fight scene, we see the view through window the moment before he goes through it; there is nobody behind him in the street. Then as he goes through the window, we see a shot from inside the diner and there is a guy standing in the street holding a stick.
Continuity mistake: When Randal has his ear cut off, we see blood on his sweater as he begins to stand up. He is then kicked into the doorframe. When he is pulled away from the doorframe and pushed towards the desk, we see that his sweater is free from blood. Then as he is lifted from the desk there's a large blood soaked stain. He is then slapped by Mr. Fouchon and we see that the stain is now even larger yet there's no blood trickling from his ear.
Continuity mistake: During the first fight scene we see Van Damme's character fighting the guys outside the diner. He moves onto the sidewalk to tackle a guy coming at him with a knife. He ducks and punches the guy in the stomach. They guy was less than a foot away but in the next shot we see the same guy running towards Van Damme from several feet.
Continuity mistake: During the scene in which the guy is bitten by the rattlesnake we see that the rattlesnake's top fangs pierce the guy just to the right hand side of his top lip. Then when the snake is pulled off and we see him lying on the floor, the bite marks are now in the centre of his cheek, and there are no bite marks for the lower fangs of the snake although they also pierced the guy's neck.
Continuity mistake: In the first fighting scene Natasha Binder's left car door and car hood get noticeable bumps. When the car reappears in the next scene the both the door and hood are perfectly smooth.
Continuity mistake: During the dirtbike chase scene, Van Damme drops the girl off, then looks down at the bike's gas tank, which has several holes and is leaking fuel. After this shot, the holes somehow disappear from the side of the gas tank, and there is no trail of fuel on the ground as Van Damme rides on (as a draining tank would leave such a trail).
Continuity mistake: Boudreaux shoots one of the men in the helicopter, and you can see him hanging out of the doorway inert his weapon fallen away. In the next shot however as the helicopter flies overhead, he's now standing upright with his weapon in his hands looking very much alive.
Continuity mistake: As Chance gets the shotgun from his uncle we see him holding it. He leans the gun to one side and then starts to blow all the dust off. As the camera angle changes, we see that the gun is no longer leaning to one side. Then when the camera angle changes again, the gun in once again leaning to one side.
Continuity mistake: In the highway chase scene, JCVD rolls over the top of a car and lands on the ground on the other side. In one of the quick shots of him raising his gun to fire, the slide is back, showing that the gun's clip is empty. But a shot or two later, the gun fires several more times nonetheless, blowing up the car.
Continuity mistake: At the end of the film, when the final shootouts take place, Van Damme is seen hitting one of the motorcyclist's with a shotgun before holding his falling body up with it. It cuts to a shot of Van Damme's face. In the next shot we see a clear view of Van Damme - but his shotgun is missing - where has it gone? He then proceeds to pull out a handgun from the motorcyclists belt and uses this to kill a bad guy from behind him - but there are still no signs of the shotgun.
Continuity mistake: Right after Fouchon refers to the "F***ing buffalo" he walks past and says "move". As soon as the camera angle changes the buffalo man's gun trades with a guy 15 feet behind him.
