3. Hannibal in the Bates Motel (Silence of the Lambs/Psycho)
If Hannibal Lecter was on the run from the law and looking for a place to stay, where better than the Bates Motel? Never mind the possibilities for gore-filled violence, the potential conversations between Lecter and Normal Bates would be absolutely fascinating. They are two men who can both pass themselves off in society as normal and sophisticated individuals who are, deep down, actually brutal psychopaths. An equally interesting scenario would be if they were in adjacent cells in a hospital for the criminally insane, trying to intimidate each other psychologically - a contest which would see the vicious, cannibalistic Lecter completely belittling the creepy Mummy's boy Bates.
