A rip off of "Dr. Jekyll and Mr. Hyde", this takes a lot of patience to tolerate Household cats become giant beasts and a moody scientist turns into a prehistoric man, growing more facial hair than the wolf-man. His friends and family suspect that something is up but let him be. When people start being attacked he feigns sympathy. Of course, where there is caveman, there must be cave-woman and that is where the film dissolve s into absolute silliness. Shots of big jungle cats passing as prehistoric cats fools nobody. As the truth of what is going on is revealed, the film moves into melodramatic drivel that seemed more appropriate for the decade before when Lon Chaney Jr. was making films like this by the dozen.
