Johnny Weissmüller traded Tarzan's loincloth for... germ warfare gorillas? Unhinged cinema awaits.
Nasty white hunters are testing out their germ warfare weapons using wild animals in Africa… until they run into Jungle Jim.
Practical Effects
The 'killer ape' suit is gloriously unconvincing rubber horror.
Acting
Weissmüller visibly calculating his residual checks mid-scene.

Director
Spencer Gordon Bennet
Trivia, insights & behind the scenes
This was Weissmüller's 13th outing as Jungle Jim—he made 16 total after aging out of playing Tarzan.
The 'man in ape suit' technique here is essentially the same used in 1933's King Kong, but with approximately 1/1000th the budget and effort.
