Prophecy (1979) is a movie that was supposed to bring attention to pollution and waste management but all it really did was come up with a Killer Bear Monster instead. There is a ridiculous death scene involving a kid wearing a yellow outfit and the killer bear's killer paw. The tagline for the movie: "She lives. Don't move. Don't breathe. There's nowhere to run. She will find you."

This is one they should definitely do as it is along the same lines as Grizzly and Day of the Animals which are two great rifftrax!
