Alas, Buffybuff: I think you are correct. John Cleese does play Nearly Headless Nick. Pity. If I could play any part in the Harry Potter Movie, my first choice would be Argus Filch. I could let my hair grow long, put a little axel grease on it and buy brown clothes.

How 'bout you? If you could play any character in the Harry Potter movies, which one would it be?
