"Lifeforce" boasts a rousing, thunderous score by Henry Mancini, it boasts some hilariously straight-faced acting, some very proficient visual effects and a generous helping of most agreeable soft porn. You could do much, much worse than check out this movie. Is it a bad movie? Maybe, maybe not. Depends on your poison. But it is unquestionably an enjoyable movie. One of those pesky, interfering space missions goes and brings a trio of "space vampires" back to Earth, one of them being a uniformly nude Mathilda May, who has a bit of a thing going on with one of the astronauts, Colonel Carlsen (a delightfully earnest Steve Railsbeck), in between feasting on the "lifeforce" (as opposed to the blood) of various extras and minor roles, reducing them to hideous, dessicated, shrieking, mindless husks that in turn seek out the "lifeforce" of other people. That is where the glorious destruction of London comes in, later on in the proceedings and very well handled for a film that endures a reputation for being amongst the worst ever made. There is imagery within those sequences that is up there with the blockbusters. "Lifeforce" has a perfectly creditable cast, including a pre "Spooks" Peter Firth as SAS Colonel Caine, Frank "Bouquet Of Barbed Wire" Finlay as one of the boffins and Patrick Stewart gobbing out a lot of blood from his mouth. The fact that they play this trash so seriously is one of the fun aspects. Oh, come on - it's trash. But it is glorious trash. It is proud trash. Trash is sometimes good, and here you have an example. "Lifeforce", the celluloid Big Mac - of no nutritional value whatsoever, but very, VERY enjoyable. Tuck in.
