Don't let the cast credits fool you. This is actually a Jungle Jim picture. Although Weissmuller is credited as playing himself, he is dressed in his Jungle Jim outfit. Moreover, the plot follows much the same formula as previous entries. Indeed it rather resembles Mark of the Gorilla, with crocodiles substituting for the apes. But though the dialogue is stilted and the situations familiar, the juvenile audience this movie is intended to please, will probably not notice. In fact the story moves at such a fast clip, it makes for a reasonably exciting diversion. Naturally, production values are helped along by a few stock shots from previous Jungle Jim entries (such as the eagle, and the underwater fight with the croc), plus quite a few clips from Columbia's library of ancient stock footage (the elephants). It all makes for plenty of action, including a fairly exciting climax. Johnny Weissmuller is his usual competent self whilst the heroine, an attractive lass, will fascinate the older boys in the audience. Unfortunately, the rest of the support players are an undistinguished lot, easily outclassed by that talented chimp, Kimba (even if he obviously doesn't really cut the prisoners free). Sholem's direction is reasonably proficient, though it provides only an occasional flash of imagination (such as the menacing crocodile shadow in the cave). The sets, however, are mighty impressive.
