I recently discovered this and was very impressed and amused by it. Starring the young Will Wheaton, who would have been in between the two roles he's most famous for (Stand By Me and Star Trek: The Next Generation), with additional footage shot by the great Lucio Fulci. I don't believe you'll have trouble determining which specific footage that is, if you're familiar with his work.
This Italian production set in Tennessee is a loose adaptation of H.P. Lovecraft's The Colour out of Space, and it achieves a nice Lovecraftian sense of existential horror as well as Southern deep-fried white trash vibe. This youtube rip, which is linked if you click the above poster image (Blogger has made embedding videos more difficult since the last time I posted) isn't the best, so I recommend you seek it elsewhere via DVD or streaming.
