Directed by Mario Bava, Planet of the Vampires is an Italian-Spanish science fiction horror film based on Renato Pestrinieros short story Una notte di 21 ore. Barry Sullivan and Norma Bengell star as space explorers who land on a mysterious planet and encounter possession, dead crew members and hostile alien influence. The film combines gothic atmosphere, alien-planet horror, space exploration and Mario Bavas stylized visual design.

In the outer reaches of deep space, the spaceship Galliott answers a distress signal from Aura, an unexplored planet. As the ship attempts to land, members of the crew inexplicably begin to attack one another. This is the start of a terrifying expedition into the unknown, one plagued by paranoia, possession and violent mayhem wrought upon the unsuspecting explorers by the planets mysterious inhabitants. A sci-fi horror hybrid from genre master Mario Bava (Blood and Black Lace), Planet of the Vampires is widely regarded as one of the most influential genre films ever made, with a clear influence on films such as Alien and Pitch Black. With a uniquely chilly atmosphere and fantastic production design that belies its low budget origins, Planet of the Vampires is a true genre classic.
