Space crew out to examine Haley's Comet bring back some space vampires that get loose and terrorize London.

Slow, poorly written and pretty boring horror/sci-fi makes little sense, has some nifty but pointless effects and is just a complete and utter misfire.

Directed By: Tobe Hooper.
Written By: Don Jakoby, Dan O'Bannon.

Starring: Steve Railsback, Peter Firth, Frank Finlay, Mathilda May.
