One of the great Horror-cum-Comedy Monster Movies of the 1950's with a typical modern science vs. Ancient superstition theme. In fact, the ancient high priestess (Inez Palange), practitioner of the "Old Ways," is the most notable thing, along with the nifty pedal-powered one man (Stuart Wade) submarine that was Corman's inspiration for the whole project. Everything else is pretty bland, and, though the Monster can't claim to be the best of the worst, when it finally emerges from the murk to menace our fair maiden (Anne Kimbell), it is laughably threatening enough to satisfy your taste for the tacky.
