Lifeforce flopped, with reviews generally negative or worse (although Gene Siskel liked it). But aided through hindsight and extended editions, Lifeforce is a geek classic. Certainly no one involved phoned it in; Hooper’s direction (never better) captures the style and dry wit of the classic Hammer Quatermass films (well worth checking out), the score by Henry Mancini (!) is appropriately quirky and bombastic, and John Dykstra’s (Star Wars) special effects are superb — the desiccated zombie design is wonderful, and the alien spacecraft is a thing of beauty. No CGI here, just craft and skill.
