The Horror of Party Beach (1964)
Where has this movie been all my life?
This movie is what the word 'Psychotronic' was invented for. It has bikini clad dancing girls wiggling it for the camera, rock n' roll (songs are actually pretty good, including 'Zombie Stomp'), bikers, mutated sea monsters with what looks like hot dogs for tongues, a slumber party massacre, and extreme (for the time) gore!
Masterpiece!!! Five Stars
