Continuity mistake: As Boudreax kicks the motorcyclist off his bike, the blue doors on the van in the background open, in a later shot, the blue doors are now closed again.

Revealing mistake: When Boudreaux leaps over the bonnet of the police car to roundhouse kick the motorcyclist off, if you look carefully in the background, there is a blue van with its back doors closed. As the motorcyclist comes to a complete halt, the blue van visibly shakes in the background and the back doors burst open. This is because the van was used as an anchor to stop the motorcyclist after being kicked off the bike.

Revealing mistake: Foucan doesn't apply grease of gel to his hair for the entirety of the movie, but after his coat gets set on fire, you can see the fire proof protective gel now covering his hair.

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.

Other mistake: Van Cleef and Boudreaux reload their guns, and then have the mother of all firefights, culminating with Boudreaux emptying both guns into Van Cleef. They only had two guns each and the amount of shots they fired apiece was way in-excess of what they reloaded.

Revealing mistake: The helicopter that chases down Boudreaux fires a shot at his horse that causes an explosion that makes it fall, then another shot is fired, but the resulting explosion is exactly the same as the previous one, except the footage is taken from a different angle.
