Lifeforce

Lifeforce, released in 1985 and directed by Tobe Hooper, blends science fiction, horror, and fantasy into a cinematic experience unlike any other. The film features the talents of Steve Railsback, Mathilda May, and Peter Firth, along with a remarkable supporting cast. Lifeforce creates a scene of terror and intrigue, demonstrating Hooper's knack for transforming ordinary narratives into something extraordinary and horrifying.

The movie is set after the launch of the space shuttle Churchill, meticulously designed by the prolific production designer John Graysmark. Steve Railsback stars as Colonel Tom Carlsen, the shuttle’s lead astronaut and mission commander. The Churchill has been sent on a mission to study Halley's Comet under the joint banner of the United States and United Kingdom. However, this otherwise scientific expedition takes a terrifying twist when the crew discovers an alien ship hidden in the comet’s tail.

The alien spacecraft features an unexplained organic design, possibly hinting towards a predatorily nature. Inside, the crew discovers desiccated bat-like creatures and three humanoid beings. The humanoid entities - two male, one female - are found seemingly lifeless in crystalline suspended animation. They are taken aboard the Churchill for further study, setting into motion a series of events which make for the gripping narrative of Lifeforce.

Mathilda May plays the unnamed female alien who becomes a pivotal figure in the film. Her performance is both captivating and chilling as she moves with a sinister grace and fascinating aura, exerting a near-hypnotic influence on others. Peter Firth stars as the hard-boiled, pragmatic Colonel Colin Caine from the British Secret Service, tasked to untangle the mysteries unfolding around the tragic fate of the Churchill crew and the now-loose alien entities on Earth.

The plot of Lifeforce paints an epic backdrop, with breathtaking action sequences and harrowing visuals. The narrative swings from the isolation of outer space to the crowded and gripped-with-terror city of London, creating a visual kaleidoscope. Lifeforce demonstrates the director's (Hooper) ability to seamlessly marry suspense and horror with elements of science fiction. Notably, the production design consistently underscores the movie's disturbing core theme, and Alan Hume's excellent cinematography lends it a visual sharpness, elevating the horror and suspense elements.

Interestingly, the film's screenplay, developed by Dan O'Bannon and Don Jakoby, is based on "The Space Vampires," a novel by Colin Wilson. They adapt the narrative to the big screen with adept skills, evident in the film's pacing and layered storytelling style. The film cleverly borrows from the vampire genre, infusing it with an unconventional twist grounded in outer space, a ruse that keeps the audience on edge throughout the film's two-hour runtime.

Henry Mancini’s remarkable score contributes to the film’s aura, setting the tone for its series of terrifying events. His compositions run the fear-inducing gamut from the celestial to the grandious understandings of horror, always heightening the tension.

The film’s visual effects, a pioneering effort by John Dykstra, bring an element of the fantastical into this horrifying tale. Dykstra's effects, which were groundbreaking at the time of the film’s release, lend credence to the stunning narrative of interstellar terror. The stunning makeup and prosthetics, on the other hand, elevate the horror elements to new heights, making the movie a crucial addition to the '80s horror film catalogue.

In conclusion, Lifeforce is a horror-filled journey that skirts the edge of reality to question what lies beyond our understanding. While the film is undoubtedly frightening, it is also deeply engrossing, anchored by strong performances from its lead cast, a mystifying screenplay, and groundbreaking visual effects. The film speaks volumes of Tobe Hooper's iconoclastic vision as a director. Though its horror trappings might not appeal to all sci-fi fans, Lifeforce is an engaging and chilling film that deserves a place in the annals of science fiction and horror cinema.
