Hmm, Jack Nicholson...I can picture him dancing down a path, babbling inSane poetry, but I think 90% of the audience would be expecting him to slit his guests' throats while they sleep or go berserk with an axe in the forest...or at least answer the hobbits' inquiries with a snarling "You can't handle the truth!" Nicholson is an orc if I ever saw one.
