When a space shuttle crew finds a mysterious spacecraft containing three human-looking creatures in a state of suspended animation, they bring them back to Earth for further investigation.

It's only then that scientists discover that they are in fact a race of space vampires that feed off people's life-force rather than their blood. So when they escape and run amok in London, the consequences are apocalyptic - and the shuttle crew's only survivor (Steve Railsback) seems to be the only man who can stop them.

Based on Colin Wilson’s novel The Space Vampires, co-written by Dan O’Bannon (Dark Star, Alien, Return of the Living Dead) and directed by Tobe Hooper (The Texas Chain Saw Massacre, Salem's Lot, Poltergeist), this lively sci-fi horror romp has a stellar cast including Peter Firth, Frank Finlay and Patrick Stewart - although it's Mathilda May's appearance as a naked female alien that attracts most attention to this day.

Lifeforce will be released on a richly featured UK Blu-ray on 30th September 2013 by Arrow Films at a yet to be confirmed RRP. The disc will also be available as a Steelbook Edition.
