By the way, it's a bit off-topic, but recently at the library, I happened across a DVD set of three Roger Corman sci-fi movies from the '50s that I don't think I've ever seen -- the 1957 double feature
Attack of the Crab Monsters and
Not of This Earth, and 1958's
War of the Satellites (which shared a double bill with
Attack of the 50 Foot Woman). I've been in the mood for vintage sci-fi lately, so I checked it out.
Crab Monsters and
Satellites are both pretty cheesy and not very coherent, with seeds of promising ideas that they don't really do anything with; the main notable detail of the former is that it gives Russell Johnson some early practice at being stranded on a desert island in the South Pacific, while the latter is notable as a rare lead role for perennial Corman company player Dick Miller. But
Not of This Earth is the one that really shines. It's a solid tale about a dying alien coming to Earth to experiment on humans to steal their blood and test whether we can be harvested like livestock to cure the degenerative disease his people have brought on themselves through nuclear war. Paul Birch makes the alien effectively intimidating and oddly sympathetic and urbane at the same time. And there are a number of nice touches to the writing, like how the doctor that the alien has hypnotically forbidden from discussing his case keeps finding subtle ways to deflect and change the subject, rather than going into some robotic trance or something.
EDIT: My favorite non sequitur from
Attack of the Crab Monsters:
Friend of hero shooting at giant mutant crab monster: "It's no use! The bullets pass through it like x-rays!"
Giant mutant crab monster, immediately thereafter: "So! You have wounded me! It does not matter, for I can grow a new claw in a day!"
