Gordon Scott's raw masculine power as Tarzan is always awe-inspiring; this time he seems to have practiced his vine-swinging too, because - when he finally does it - he is not doubled. And he is aided by a strong supporting cast - especially an already charismatic pre-Bond Sean Connery. This is a gritty, violent (for the era), well-paced and well-shot adventure-thriller, although the stock footage of real animals is still glaringly obvious. If there is something remarkable about this story, it's that Tarzan doesn't really have to do much; his mere presence causes the bad guys to disintegrate by themselves. **1/2 out of 4.
