Lifeforce (1985)
The major selling point for this movie is the main character: a nude lady vampire from outer space. She’s not of this earth, she’s a vampire and female and she’s totally naked – for the entire movie. Rather than sucking her victim’s blood she sucks out their life force, leaving behind shriveled-up carcasses, all the while wearing not a stitch of clothing – which is probably how they get around in outer space. The novel on which the movie is based features a nude lady vampire from outer space only at the beginning but the makers of the movie knew better and she’s nude all the time. There are lots of hammy performances, zombies and monsters and a score by Henry Mancini but, really, for fans of unearthly, undead, undressed women, there’s no better movie in the entire universe.
