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.

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