Revealing mistake: Near the end, Dundee captures Rico (the bad guy) and changes clothes with him. Dundee is at least 6 inches taller than Rico, yet the traded clothes fit both men perfectly.
Continuity mistake: When the first two baddies are captured they are tied up back to back in the cave. Next time they are seen, they are side by side.
Continuity mistake: In the cave, Sue tells Mick that the rifle has no more ammo, but when she goes to help Mick, she shoots the bad guy with the very same rifle.
Question: If the crocs in this movie are saltwater crocodiles, why is the lady sipping then filling her canteen with saltwater? Later when swimming with Dundee in freshwater, no crocs.
