Revealing: When our heroes are in the hut, with the African warlord, there is a lot of money. At a time, they throw an bundle of dollar bills, and the top-bill flips over, and shows that the next is just plain white paper.

Factual error: In the scene in the cave where they finally found the white diamonds, they take the diamonds from the stone-mine-wall with their fingers and the diamond is alredy cut like a jewel (diamonds in their "raw" form look like rough glass).

Continuity: 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.

Continuity: When Dr. Elliot hugs Amy, after she finsihes painting, the position of Amy's head on his shoulder keeps changing between shots.

Plot hole: Karen asks Charles' if she can have his co-ordinates for a later link-up. However later we see her able to operate the camera herself remotely.

Continuity: When Homolka is telling Dr. Elliot about not being able to afford the plane fuel, the buckle on his bag strap moves between shots.

Continuity: 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: Bodies are left in the mines, for example, Homolka's, yet when the lava flows through, the bodies have vanished.

Continuity: When the plane is hit by missiles, Munro gives Amy a drugged banana to sedate her. Between shots the length of the banana changes.

Continuity: 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: When the group leaves the African airport in the truck, the hole in the truck roof is closed, then open in one interior shot, then closed again.

Continuity: At the start of the film, one of Jeffreys eyes is ripped out. Later when his corpse is found by Dr. Ross and Elliot, he has both eyes in his corpse.

Continuity: When the group arrive at the plane, the ground around it differs from wet to dry and the shadows around it also change a few times.

Continuity: When everyone is at the second plane, Munro opens a box which is completely in sunlight. In the next shot it's covered in shadow.

Continuity: When the first missile hits the plane, Richard holds onto and comforts Amy twice between shots, as the plane begins to rock violently.

Continuity: When Dr. Elliot and the group arrive at the plane, the plane changes position between shots, in relation to the trucks surrounding it.

Visible crew/equipment: As the team walks through the ruins, a flock of birds bursts out of a bush. You can see a persons arm shooing them out.

Continuity: When Dr. Elliot is faced with the Silverback gorilla, the size of the sweat stain around his collar and shirt changes throughout the scene.

Continuity: After the Travicom boss smashes the TV screen, the right side of the screen is on fire. In the next shot the left side is now the side alight.

Continuity: When the boss says to Dr. Ross "So Where is He!?" [about Charles], his hands go from by his side, to on his golf club between shots.
