Planet of the Vampires (Italian: Terrore nello spazio) is a 1965 Italian/Spanish science fiction horror film directed by Mario Bava. The film stars Barry Sullivan and Norma Bengell. The screenplay was based on an Italian-language science fiction short story, Renato Pestriniero's "One Night of 21 Hours".

The story follows the horrific experiences of the crew members of two giant spaceships that have crash landed on a forbidding, unexplored planet. The disembodied inhabitants of the world possess the bodies of the crew who died during the crash, and use the animated corpses to stalk and kill the remaining survivors.

Years after its release, some critics suggested that the film's narrative details and visual design appeared to have been a major influence on Ridley Scott's Alien.

The Plot:
In the near future the two spaceships are sent to investigate the mysterious planet Aura. As the ship lands on the planet her crew suddenly go berserk and attack each other. the explorers come to realize the existence of a race of bodiless aliens that seek to escape from their dying world.
