aw, no kh marathon? ):

I'm not much of a movie person, but I second the Donnie Darko recommendation. Try to avoid the Director's Cut; the pages of 'The Philosophy of Time Travel' randomly inserted between scenes are really annoying. Plus it's more fun to read the pages at the Web site.

-Also Air Force One.
-The Godfather is a given but I've never been able to sit through that movie, personally.
-The original Halloween is good for a laugh
