Other mistake: The end credits are plagued by the biggest compilation of spelling mistakes you'll ever see. The French cast in particular has 2 out of 2 actors with their names wrong (PallarOy instead of PallarDy, a female, Danièle, turned into a male Daniel) and so many errors in the technical cast to make some of them impossible to identify.
Other mistake: During the fight on the dam between von Ragnar and Lance, the protective cover of von Ragnar's deadly middle finger nail is never seen until the closeup shot of von Ragnar removing it.
Other mistake: Lakella seems to disappear from the movie after the battle.
Other mistake: Harry Shannon tells Mark Kaminsky that the alias he is giving him is that of Joseph P Brenner which to a guy with a long rap sheet. Paulo Rocca later asks Joey, "how the hell is it you never did any time?" (00:20:56 - 00:39:53)
Other mistake: The spot light from the school building spotted the scuba divers with yellow oxygen packs, but the guerrillas did not respond.
