What's become the necessary intro shot of forest deer overlooking the water appear here again, this time watching Tarzan et co on a raft; deer are not native to Africa.
There are several shots showing tapir. Tapir are not found in Africa, as they are native to South America.
Other non-native featured animals to pass as African include bears.
This time the extras featured as African natives aren't Black at all: they appear to be Indonesian or Filipino.
The elephants shown in early scenes are Indian elephants, not African.
Tarzan's knife has the ability to appear and disappear between shots. In one scene, he throws his knife at a hunter on the ground, hitting him in the back. A moment later, he goes to attack another man, and lo and behold, the knife has returned to its sheath. A second later, when the shot changes, the knife is gone again. And, after he defeats the man in the tree and runs off to save everyone else, the knife is back in its sheath again without Tarzan going to retrieve it from the man he threw it at!
Although living in the African jungle for many years without the benefit of sunscreen, Tarzan, Jane, and Boy all have lily white skin.
In the final scene, Cheetah drops from the airborne plane in a small chimp sized parachute, an unlikely item to be stowed on the plane.
Several times Cheeta is referred to as a female. But, in the the scene where Cheeta performs cartwheels, as well as other scenes, it is obvious that Cheeta is a male.
