Although the remake with Sam Rockwell and Rosemarie DeWitt is currently in cinemas, the original's definitely worth a watch. Craig T. Nelson and JoBeth Williams are two parents who downsize their house and get more than they bargained for when they discover their home is host to a poltergeist. Directed by Tobe Hooper and produced by Steven Spielberg, there's endless amounts of urban legends about this film. Forget all that - this is a horror classic.
