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.

Directed by: John Woo
Starring: Jean-Claude Van Damme, Lance Henriksen, Arnold Vosloo, Yancy Butler, Chuck Pfarrer, Robert Apisa
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!
