Character mistake: When the group is escaping from the killer gorillas, they find a cave and Ross say "It's a geode, a giant diamond." A geode is not a diamond at all, it's basically a hollow rock with crystal formations inside.
Continuity mistake: Bodies are left in the mines, for example, Homolka's, yet when the lava flows through, the bodies have vanished.
Continuity mistake: When Munro and Dr. Ross talk to the borders cheif, the same people can be seen walking past the window behind him, multiple times.
Continuity mistake: When Amy knocks down the satellite equipment she merely bumps it and it falls over. But in the next shot it is completely smashed to pieces.
Continuity mistake: When Homolka has to jump out of the plane, he first sticks his head out the door. The exterior shot shows that his left hand is holding onto the plane but not in the interior shots.
Continuity mistake: On the plane the drug is put into a broken banana half, but when it's time to jump out of the plane Amy is given a whole banana.
Suggested correction: I think it's safe to say they either put the banana halves back together to help hide the pill or erred on the side of caution and gave two doses in a second banana.
Continuity mistake: As the expedition sets out after collecting their parachuted gear, the scenery instantly changes from Savannah in the shot with Elliot and Munro to deep jungle in the shot with Amy and the chameleon.
Continuity mistake: In the meeting with captain Wanta, when the soldier takes Homolka and lift him, the pile of money is tumbled. When Wanta takes it, it's up again.
Other mistake: When in the jungle, Elliot says to Amy "Let's turn your volume down" and makes an adjustment to Amy's backpack voice synthesizer. A few seconds later Amy "speaks" at exactly the same volume as before.
Revealing mistake: When the missile destroys the second airplane after everyone has escaped, the airplane suddenly stops moving forward. In the next shot where we see a close-up of the explosion, it is also stationary against the sky.
