Director: Wes Craven. Cast: Louis Jourdan, Adrienne Barbeau, Ray Wise, David Hess. 91 min. Rated PG. Horror.
Cheesy fun B-movie classic, about a man-plant monster who is the result of a scientific experiment gone wrong, and displays delightfully terrible makeup effects. But to be honest, I'm not sure if the whole movie was about the monster, or the monster's love interest Adrienne Barbeau (John Carpenter's wife at the time) in a very crucial scene - namely, the scene that was edited out in the newer cleaned-up version. You be the judge.
PS: Debating whether to watch the sequel, The Return of Swamp Thing (1989).
