PLANET OF THE VAMPIRES 1965 (MGM)

Originally released with "Die Monster Die", this eerie film directed by Mario Bava stars Barry Sullivan as the leader of a party of astronauts who land on a mysterious planet and soon find themselves fighting for their lives against unseen alien beings who are looking for bodies to inhabit and a new planet to live on.
Ridley Scott ripped off some of the ideas in this film for Alien and did very well with them such as the distant SOS signals being sent and the huge skeletons that Sullivan and co-star Norma Bengell find as they search the planet.
A very good and atmospheric film. The best sequence in the film comes when the dead bodies out the astrounats come out of their graves. Bava was and always will be the Master of Italian Cinema. Recommended!!
