Two Thousand Maniacs
The inimitable Herschel Gordon Lewis offers us a warped variation of Brigadoon in his "chef d'oeuvre" 2000 Maniacs. A bunch of dull, faceless young folks wander into a strange southern town. Here the strangers are systematically tortured and butchered by the town's congenital-idiot residents. It turns out that the villagers are the ghosts of Confederate soldiers, exacting revenge for the Civil War. Admittedly, the various methods of murder are inventive, and there is a hint of tongue in cheek. Still, 2000 Maniacs is a Herschel Gordon Lewis production, which should be warning enough.
