The spaceships Argos commanded by Captain Mark Markary (Barry Sullivan) and her sister Galliot commanded by Captain Sallas (Massimo Righi) travel to the mysterious planet Aura to investigate a strange transmission of a distress signal. The spaceships are protected by the meteor rejector instrument but on the arrival, the gravity increases and the automatic controls go haywire and the Galliot crashes on the surface of Aura. Then the crew-members in Argos go crazy and attack each other in a first moment. Soon Captain Mark finds that most of the crew from Argos is dead after fighting against each other. When the dead members resurrect, Captain Mark, communications officer Sanya (Norma Bengell) and engineer Wess (Ángel Aranda) discover that parasite bodiless aliens have entrapped them with the transmission expecting to flee from their dying world. What will be their attitude?
"Terrore nello spazio", a.k.a. "Planet of the Vampires", despite the low- budget, is an original, stylish and with a surprising plot point. The conclusion shows a great surprise to the viewer. This movie was certainly the major influence to at least Ridley Scott's "Alien" and "Prometheus" that have similar storyline. It was said that the set was a Tower of Babel, with international cast using their own native language (Barry Sullivan, English; Norma Bengell, Portuguese; Ángel Aranda, Spanish; and Evi Marandi, English). My vote is seven.
Title (Brazil): "O Planeta dos Vampiros" ("The Planet of the Vampires")
