Audio problem: Just after the captain of the other boat (Bill's friend) breaks the bottle, and looks over the side, you hear a voice say "What the hell was that" although the guy's mouth doesn't move, also the voice sounds more like Bill's low voice than this guy's Australian-sounding accent.
Factual error: After the scene where they fall over the waterfall, and go through what they have left of the equipment. Bill, the Latino doctor, holds up the CD-reader from a desktop computer and says that the hard drive is broken, which would be OK if he actually had the hard drive present. (00:34:35)
Cole Burris: I'm so hungry, I'd sell my Grandmother for a tic tac.
Trivia: The Chinese tattoo on Bill's arm reads Wo de shi jie, which means "My world."
Question: Do the giant snakes look better in this sequel than in the 1st movie?
