Another iteration of the Jekyll & Hyde / werewolf story, given a patina of ’50s respectability and pertinence by dint of that ol’ debbil Radiation. The movie came about because star Robert Clarke had, to his surprise, made a batch of dough from his 5% of the profits from The Astounding She-Monster. Figuring he could make a film as good or better than that one, he laid out a big five hundred bucks for a cool monster suit (built on a wetsuit, so that he sweated like crazy during the shoot) and went to work, directing as well as acting. Sadly, the company that distributed the film went out of business 18 months later, and ate his profits, ending his production company. Still, people fondly remember the film (Tom Selleck one called it his guilty pleasure), and the character lives on in a very minor way.
