Director Tobe Hooper adapts Colin Wilson's edgy novel
The Space Vampires
in this in this horror/sci-fi epic with a cult following. The story concerns a joint British-American space probe of Hailey's Comet. Inside the comet, the astronauts, headed by Carlsen (Steve Railsback), find a spaceship that contains the dead bodies of several aliens, along with the naked bodies of three human-like creatures in suspended animation. They bring the aliens aboard the ship for examination, but the specimens are sloppily guarded and soon the trio spread contagion among the population of the ship. Returning to earth, the beautiful space vampire (Mathilda May) escapes into London and begins to feed of the bodies of the unwary Britons, turning the city into a zombie-populated wasteland. It is now left for Carlsen to stop the vampire invaders.
