Not of This Earth (1957)
"An alien agent from the distant planet Davana is sent to earth via a high-tech matter transporter. There he terrorizes Southern California in an attempt to acquire blood for his dying race, the result of a devastating nuclear war."
First time I watched this,I thought it was ok...second time I thought it was pretty good and third time I loved it.
Corman again succeeds in delivering a bizarre and entertaining film on a very tight budget imho.
