One of the most bonkers movies of Texas Chain Saw Massacre director Tobe Hooper‘s career will have a new streaming home next month. Lifeforce, Hooper’s cult classic space vampire epic that helped topple one of the wildest movie studios of the 1980s, is coming to Prime Video. It will be available to watch on the streamer starting September 1. An adaptation of the 1976 Colin Wilson novel The Space Vampires, 1985’s Lifeforce was the first film Hooper made on a three-film contract for Cannon Pictures, the 1980s premiere producer of B-movies, from Ninja III: The Domination to Breakin’ 2: Electric Boogaloo.

Lifeforce boasted an impressive pedigree: In addition to Hooper, who was fresh off directing the horror hit Poltergeist, its script was co-written by Dan O’Bannon, of Alien and Return of the Living Dead fame. Its $25 million USD budget was uncommonly hefty for the spendthrift Cannon, whose films typically relied on the low-cost talents of Chuck Norris or Charles Bronson. It only made back $11 million of that budget, and currently holds a 58% rotten rating on Rotten Tomatoes. Furthermore, its financial failure, along with several other big-budget Cannon bombs like Masters of the Universe and Over the Top, eventually led to the demise of the scrappy studio.

What Is ‘Lifeforce’ About?

The film kicks off when a space mission commanded by Tom Carlsen (Steve Railsback, Helter Skelter) encounters a massive, ancient alien spaceship hidden in the tail of Halley’s Comet. Inside are three pods containing a seemingly humanoid trio of aliens in suspended animation. The mission becomes a disaster, with Carlsen the only survivor. The female alien (Mathilda May, who spends most of the movie completely nude) soon breaks loose, draining the lifeforce out of everyone she encounters. Together with Carlsen, who now has a psychic link to the female alien, scientist Hans Fallada (Frank Finlay, The Pianist) and SAS Colonel Colin Caine (Peter Firth, Equus) try to track her down before she can unleash a vampire apocalypse on London. The film also features a pre-Star Trek Patrick Stewart, who has a spectacularly gruesome death scene.

Thanks to Hooper’s gonzo sensibilities, Lifeforce has become a cult classic over time. His other two Cannon films, a remake of the 1950s science fiction classic Invaders From Mars, and Texas Chainsaw Massacre 2, a bravura sequel to his horror breakthrough, have likewise found their audiences with the passage of time.

Lifeforce will stream on Prime Video starting on September 1. Stay tuned to Collider for future updates.
