Lifeforce is a 1985 science fiction horror film directed by Tobe Hooper, adapted by Dan O'Bannon and Don Jakoby, and starring Steve Railsback, Peter Firth, Frank Finlay, Mathilda May, and Patrick Stewart. Based on Colin Wilson's 1976 novel The Space Vampires, the film portrays the events that unfold after a trio of humanoids in a state of suspended animation are brought to Earth after being discovered in the hold of an alien space ship by the crew of a European Space Shuttle. The film received negative reviews on release and was a box office failure, but has since become a cult film. Plot The crew of the joint British and American Space Shuttle Churchill, under the command of Colonel Tom Carlsen, finds a spaceship hidden in the coma of Halley's Comet. Inside, the crew discovers hundreds of desiccated bat-like creatures and three naked humanoid bodies (two male and one female) in suspended animation within glass containers. The crew recovers a bat-alien and the three bodies and begins the return trip to Earth. However, during the return journey, mission control loses contact with Churchill. A rescue mission is launched to investigate. The rescuers discover that Churchill has been gutted by fire. The present crew are dead, and the escape pod is missing, yet the three containers bearing the bodies remain intact. The bodies are taken to the European Space Research Centre in London. Prior to an autopsy, the female alien awakens and drains the life force out of a guard. She then escapes the facility and proceeds to drain other humans of their life force. The two male vampires awaken and attempt a violent escape, but they are apparently destroyed by grenades thrown by the guards. Soon after, the guard revives two hours after his death and also displays the ability to drain others of their life force. Meanwhile, in Texas, an escape pod from Churchill is found with Carlsen inside. Carlsen is flown to London, where he describes the course of events, including feeling compelled to open the female vampire's container and share his life force with her, culminating in the draining of the Churchill crew's life force. Carlsen explains that he set fire to the shuttle with the intention of saving Earth from the same fate and escaped in the pod. However, when he is hypnotised, it becomes clear that Carlsen possesses a psychic link to the female alien,
