Colonel Carlsen (Steve Railsback) and the crew of the shuttle Churchill discover an alien ship attached to Halley's Comet, go inside it and find a bunch of dead oversized bats, a naked woman (the gorgeous Mathilda May ... what have I always said about French actresses?) and two males and take them back with them, except this unleashes unspeakable damage on the residents of Planet Earth.  It's a curious mashup of genres - sci-fi! vampires! zombies! - into one bloated whole: Golan and Globus gave Hooper (and screenwriters Dan O'Bannon and Don Jakoby) a budget of $25 million (adjusted for inflation: $59 million in 2019) to adapt Colin Wilson's novel The Space Vampires and this is what they were handed, a box office dud with some not-bad special effects work by John Dykstra and a hammy performance by Railsback.  It fully exhausts itself well before the conclusion, in which St. Paul's Cathedral blows up and all of humanity is turned into extras from a George A. Romero film.  I'll grant it this: it tries and it does not succeed, but you'll never forget it.
