ScottC sent this over to me and I swear I have seen the entirety of this film before. This is taken from The Adventures of Mark Twain and is truly a disturbed piece of work. You can read the Wikipedia article here. It's by the same guy who did the California Raisins, Will Vinton. And although this clip doesn't have the voice, that's James Whitmore from Shawshank Redemption as Mark Twain.
