Goofs

During the sandstorm after their escape from the city, Tarzan and Boy can be seen wearing footwear of some kind, yet a moment later when they leave to seek shelter, they are both barefoot again.

When we first see Tarzan he is swimming in his loincloth. As he speeds through the jungle to fetch Jane's air mail letter he is seen swinging on a vine in an over a shoulder caveman outfit. When he arrives at the mail drop he is back in his loincloth.

Tarzan throws a knife and pierces the magic box where Connie is being sawed in half. When Tarzan goes to open the box to release her, the knife hole is gone.

When Tarzan and Boy walk across the hot, sandy desert on their way to get the medicine from the jungle, they both walk across it in their bare feet. Sand often gets extremely hot out in the desert, and both of them should be suffering from burns on the bottoms of their feet, but they do not.

There are no Pintos in Arabia.

During Connie's escape from the hanging, when she jumps on the horse behind Tarzan her hands are tied securely behind her back for the hanging, but she cannot hold on like that. She is subsequently shown with empty sleeves tied behind her back as they gallop away, and then with her arms behind her again as she sheds the rope (clearly not tied at all) and grabs onto Tarzan.

When Cheetah lands with the airmail canister, its parachute is not fully open, and it is obvious the chimp is being lowered to the ground on a cable attached to the canister and parachute.

Tarzan and Boy are trekking through a hot desert, but neither of them show any sweat.
