A Roger Corman Drive-In special. Before the Enterprise had a matter transporter, the planet Davana had one of their own. Seems Earth isn’t the only place with nukes. Someone on Davana dropped the big one and an agent was sent to Southern California to get some blood for the leftover Davanians.
The agent calls himself Paul Johnson and moves in with a nurse and her servent. They start getting edgy when people come to the house but don’t leave. Even space vampires need some refreshment.
Paul Birch is very good as the alien. He played Captain Carpenter on “The Fugitive” 1963-64. The nurse is Beverly Garland. TV fans know her as Barbara Harper Douglas on “My Three Sons”, as Cookie LaRue on “Mary Hartman,Mary Hartman”, Dorothy “Dotty” West on “Scarecrow And Mrs. King” and as Estelle Reese on the soapie, “Port Charles.”
Corman favotite Dick Miller plays a vacuum cleaner salesman.
