Tarzan and the Lion-Man

Tarzan and his lion companion Jad-bal-ja discover a mad scientist with a city of talking gorillas. To create additional havoc, a Hollywood film crew sets out to shoot a Tarzan movie in Africa and brings along an actor who is an exact double of the apeman, but is his opposite in courage and determination. Later, as John Clayton, Tarzan visits Hollywood to find himself in a screen test for a role in a Tarzan movie. He is deemed unsuitable for the lead role because he is "not the type."
