I'm glad to see Shawshank get some love...a lot of it was filmed in Ohio. The courtroom scene at the beginning was filmed at the courthouse I had to appear in when I got my underage speeding ticket. It was very, very weird to see that.
If I had to choose three, it'd probably be up there with Pleasantville, Clue, and maybe Pulp Fiction. I'd need to think about it.
