Continuity mistake: When the first missile hits the plane, Richard holds onto and comforts Amy twice between shots, as the plane begins to rock violently. (00:36:40)
Continuity mistake: When the plane is hit by missiles, Munro gives Amy a drugged banana to sedate her. Between shots the length of the banana changes. (00:36:50)
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)
Continuity mistake: When Munro talks to Homolka at the campsite, about Dr. Ross, Homolka's cigarette jumps from his mouth to his hand between shots. (00:43:05)
Continuity mistake: When Dr. Ross is transmitting to Houston, she is holding her headset, but on the video screen in Houston, she isn't holding it anymore. (00:45:00)
Continuity mistake: When the two Ghost Tribals step out from the bush, the amount of white makeup all over them signifcantly increases between shots. (00:49:10)
Continuity mistake: When Dr. Elliot is faced with the Silverback gorilla, the size of the sweat stain around his collar and shirt changes throughout the scene. (01:02:30)
Continuity mistake: As the group enters Zinj, a black man leads. As he walks through a cave, he is holding nothing. In the next shot he has a machete and gun. (01:05:50)
Continuity mistake: After the diamond mines of Zinj are found, Homolka gathers up the diamonds. When he asks Kelly to help, his hands change positions between shots. (01:26:54)
Continuity mistake: When the lava erupts out of the mine, it hits some gorillas. In the next shot, the lava covers the same stretch and hits the same gorillas. (01:27:55)
Continuity mistake: Nearer the end, sometime during the catastrophe in the mines, Dr. Elliot gains a large bruise on his forehead. This has later completely vanished.
Continuity mistake: Near the beginning the huge headquarters for the corporation that Dr. Ross works for is shown located in Houston. In shots you can see mountains, but the problem is that there aren't any mountains in Houston.
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.
