Lifeforce (1985)
Astronauts send lifelike humanoids from the interior of Halley's Comet down to Earth for examination. The creatures break loose, spreading a weird kind of vampirism that leaves its victims grotesquely deformed. Director Tobe Hooper ("Texas Chainsaw Massacre") teamed up with special effects wizard John Dykstra ("Star Wars: A New Hope") for this creepy adult horror fantasy.
