Admittedly, this has been written about elsewhere so I'm just rehashing here. Do NOT attempt to watch this before 2:AM. Then, this movie will cause you to doubt your sanity. By the amazingly inept late great Al Adamson (who I met at a horror convention mere months before he was murdered in his own home) The plot? Forget it! Suffice to say it's got (ridiculous looking) vampires, spaceships, lotsa cavemen and cave women, lobster men, and some proto-cyber-sex (sort of) A great movie to fall asleep in front of. With John Carradine.
