Shot on a miniscule $50,000 budget, and including footage from a 1959 Russian film that was later purchased by Roger Corman, this science fiction feature finds a tiny planet slowly dying. With the inhabitants in danger of perishing, some kind-hearted astronauts bring a green-blooded female alien back to Earth. The extraterrestrial shows her gratitude by going wild for human blood in the fashion of a blood-sucking vampire. John Saxon, Basil Rathbone and Dennis Hopper are some of the actors sentenced by their vindictive agents to appear in this 1966 film.
