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.

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.
Continuity mistake: Just before Homolka jumps out of the plane, he puts his right hand on the side of the door and his left hand is holding his bag. In the next shot the hands have reversed roles. (00:37:05)
Revealing mistake: When the group is in the mines and there is a cave in, one of the porters is hit on the back by a (fake) rock, which bounces off. (01:21:05)
