Tarzan has been unconscious but comes round, drinks some water and splashes some over himself, the camera switches to Mary then back to Tarzan and he's unconscious again with Cheetah trying to pour coconut milk into his mouth.

Tarzan's Loincloth is not wet when he and Mary get out of the water after the crocodile fight and in some shots her arms and legs are dry in others they are wet while her hair is always dry.

Near the end of the movie, Tarzan is swimming and then climbs out of the water. It is clear that he is wearing actual swimming trunks instead of the loincloth seen in other scenes.

in the shots of Mary during the fight Tarzan has with the crocodile. Mary doesn't appear to be scared.

When Tarzan yells after he fights the Lion at the start of the movie. Tribe members are shown running through the trees. Mary, who hasn't arrived in the jungle yet can be seen in the background.

Not only are the elephants Asian not African, but the crocodiles are alligators, and the river Mary swims in is nowhere near Africa, but in the American west.

As with almost all Tarzan films, the elephants shown are Indian elephants, not African elephants.

After Tarzan Wrestles and defeats the crocodile and Mary and Tarzan are back on land. Tarzan pulls a note out of his loincloth. It would have been ruined from being in the water.

The crocodile doesn't react when Tarzan swims up to it.

The crocodile chasing Mary and trying to eat her is clearly fake.

Shots often cut back and forth from thick jungle forests to open-range savannas. These locations in Africa are 1,500 miles apart.

Mary and her group are walking through the jungle without horses. Mary is kidnapped by some villains from her group and they have horses to take Mary away.

Tarzan may be fearless, but he cowers embarrassingly at the sound of recorded music.

In the swimming scene with the crocodile. Mary tries to escape by swimming away with the crocodile following her. Tarzan dives into the water to rescue her and catches up to the crocodile before it can reach her. Tarzan and the crocodile fight. Mary watches the fight and doesn't try to escape.

In the final fight with Tarzan and Jeff. Jeff shoots at Tarzan and Tarzan is pretending to be dead on the ground as Jeff approaches him. Tarzan's body is still moving as he breathes. Jeff would have been able to see it and finish Tarzan by shooting him and not coming close to him.

Tarzan uses his knife when in combat with the Lions and Alligators, but doesn't use it against the human enemies in combat with them.

When Mary meets Tarzan, she asks him why he doesn't answer her questions. She was told by her group earlier that he is a wild man raised by apes.
