Before Kimba goes off to spy on Tarzan and later befriend him, Lea and Kimba are both talking in front of a mirror, approximately two feet from each other. When the camera pans back for a wide shot, they are both further apart.
When Cheetah sneaks up on the Commissioner and Doctor Lazar, he sprays the Commissioner with the soda water from the bottle on the ground. You see him hit squarely in the face with the water, yet right after he gets up from his chair, his face and clothes are dry.
When Boy finds the Leopard Man costume in the cave he tries it on. As he picks it up the steel claws attached to the arms fall onto the rock near where he is standing. The sound heard is that of an empty wooden or fiberglass box. It can he heard two or three times as the claws bounce against the prop.
The elephants depicted are Indian elephants, not African.
There would be no reason for Tarzan to build the elaborate "shower bath", that continually breaks down, when they have endless river water to bathe in.
