aka The Giant Leeches
How bad is it? It's a typical low budget 50's monster movie.
Should you see it? Yes. It has a sleazy charm. It's not particularly laughable, though.
Yvette Vickers (Playboy's Miss July 1959), fresh off of playing the town slut in Attack of the 50 Ft. Woman (reviewed earlier), plays the town slut here as well. She's the two-timing wife of Bruno Ve Sota, the town sheriff who has a problem with people disappearing into the swamp amid rumors of monsters. The monsters are real, being giant intelligent leeches, played by men whose rubber suits don't fit well over their scuba tanks. There are a few effective chilling moments, such as when Ve Sota forces Vickers and boyfriend into the swamp at gunpoint.
