After a bearer gets shot, Martin, Harry, and the other carriers hide behind a thicket. One bearer has two shotguns on his right shoulder. In the following shot, he appears with one shotgun on each shoulder.
Harry and Martin climb the rocks toward the top, where the monkeys are, carrying the rifles on their shoulders. But next shot, when Harry is shown from above, he is holding the rifle leaned on the top.
When Martin and Harry are talking around the table, Martin holds the pipe with his right hand about his belly. From one shot to another, his right hand appears about his chest and, subsequently, holding the pipe in the mouth.
The bole, on which Cheetah floats in the river, changes from one shot to another.
Jane lies in front of two furious lions with her back next the rock. The following shot, just from the rock side, shows that she is a little way from the rock.
(at around 12 mins) When the safari is traveling along a river, a vehicle can be seen traveling along a road high on the other side of the river.
Throughout the film, the trapezes Tarzan swings on can be seen.
When fighting the lions, Jane repeatedly fires a single-shot bolt-action rifle without reloading it, as though it contained a clip. When she finally runs out of ammo, she ejects the last shell and looks at the empty chamber as if checking for another round. But when she lays the rifle down, it can be seen that it does not have a clip or even the opening for one.
When Tarzan raises Martin from the ground, the wire caught on his back can be seen.
Obviously fake Cheetah on Tarzan's back when he swims the river. It is strapped to his neck and swings wildly to the left and right as Tarzan swims, but Cheetah itself does not move.
The first time Tarzan's yell is heard, Harry says something to Martin. He moves the lips, but no sound is heard.
When the explorers are fighting against the Gaboni people, Harry positions the rifle and pulls the trigger, but the rifle does not fire. After they cross the river, Martin finally shoots, but no sound is heard.
When the lioness appears in front of Jane, she screams to call Tarzan. Then Tarzan gives his yell while swimming, and his mouth being covered/uncovered by water.
