This lays claim to being the worst of the "Jungle Jim" series. Normally these films are mildly enjoyable escapism which compensate for a low budget with imagination. The best of the scribes is frequently Carroll Young, but this time his flair has deserted him. This film is just plain stupid. It is easily possible to lose track of the number of times characters have their back turned and are looking in the wrong direction when the ape man attacks. The story goes round in circles with characters being attacked, tortured, escaping and then being recaptured in ridiculous circumstances. Plot threads go nowhere such as the lynch-pin of the story which opens with crocodiles behaving oddly. Potentially this is quite an original idea (and was probably used because producer Katzman had some stock footage he wanted to insert), but after an early scene no further mention is made of this. Carole Thurston does one of her patented native girl characters. The title character does not look like an ape more like a big moron clothed in a dress from a charity shop. Best acting comes from the chimp!
