10 Star Trek Legends Who Starred In Horror Movies

This movie comes from horror icon Tobe Hooper, the director of Poltergeist and the original Texas Chainsaw Massacre. Lifeforce came two years before Patrick Stewart would take the role of Captain Jean-Luc Picard in Star Trek: The Next Generation. Jean-Luc is a role he would play across 176 episodes and four movies, and later his own series, Picard.

Three shapeshifting vampires, one female and two males, are found by astronauts in a comet and brought to Earth. Instead of feeding on blood, they drain their victims of their lifeforce. Stewart plays Dr. Armstrong, a hospital manager whose body is used as a hiding place by the perpetually nude female space vampire. The aliens transform a large part of London’s population into zombie-like creatures, causing chaos in the capital. This movie also features Stewart's first on-screen kiss, shared with co-star Steve Railsback. Lifeforce is based on the 1976 sci-fi novel The Space Vampires.

This film was produced by The Cannon Group, a company famous for releasing movies such as Cobra, Superman IV: The Quest for Peace, Masters of the Universe and a string of Chuck Norris action flicks. Lifeforce, costing approximately $25m, may have been the studio’s most ambitious release.
