Shot back-to-back in the Philippines with the dreadful Daughters of Satan, this is a surprisingly imaginative and topical revamping of The Hounds of Zaroff. In this version, the Zaroff character becomes a well-intentioned medical researcher (Littler), who is forced to use a big game hunter (Lauter) in order to track and kill the human animals that result from his experiments on incurable psychopaths. The direction is stylish and ambitious, and Schenck doesn't altogether skate over the issues raised by the plot. In particular, he reserves a memorable coup for the climax, in which the scientist/hero mistakenly swallows his own serum, is transformed into an apeman, and then abandoned by the heroine to roam through the jungle in solitary splendour.
