Once again, the African jungle proves to be THE place to find hot, English speaking women: not only is it home to Jane, who has finally returned from Europe after extensive plastic surgery and a dye job, and Princess Zandra of the hidden city of Palandria (from Tarzan Triumphs), but it's also where a tribe of gorgeous, brunette, man-hating Amazonian warriors live in secret, in yet another hidden city situated behind a huge range of mountains (quite how they got there from South America is never really explained).
When Tarzan refuses to reveal the whereabouts of the city to members of a scientific expedition, Boy stupidly decides to help them, and before you can say 'Ungawa', the Amazon women have themselves some new workers to toil in their fields. Unwilling to spend the rest of their natural lives in slavery, the men attempt a daring escape, but as they are leaving, several members of the expedition unwisely decide to help themselves to some of the tribe's gold and its not long before the angry women are in pursuit with arrows a-flying.
A definite improvement on Weissmuller's previous adventure, Tarzan's Desert Mystery, this film wisely goes back to basics with a standard jungle setting, untrustworthy outsiders, animal hi-jinx from Cheetah, and even a good old crocodile wrestling scene! It might not be all that original, but it's never boring. If the ending hadn't been so weak, with Tarzan turning up at the city long after the party has finished and happily collecting Boy from the Amazon women without a fuss, this film would have been a straight 7/10. Instead, I give it 6.5 (which gets rounded up to 7 for IMDb anyway!).
