Factual error: When Rambo plays possum then suddenly takes out the Russian officer's Hind Helicopter he uses an M72A2 light anti-tank weapon (LAW). When fired, the M72A2 has a back blast that can kill out to 100 feet, which means he would have either blown up his own helicopter or killed all the MIA's he had rescued...
Revealing mistake: In one scene, when Jack is in the dungeon talking to the fairy, you can clearly see that the "fairy" is nothing more than a light on a thin piece of wire. The wire can be seen quite clearly for two shots.

Continuity mistake: When the Antereans go into the sea for about the second time I think, Jack stays on the boat and starts playing about with the machine and makes it go off.

Continuity mistake: When Mad Max is sent on gulag on a horse, they place a jar of water on a stick tied to the horses head in order for the horse to keep walking "towards" it.
