Boy that's a tuff one. I think I have about 20? I'll just pick the one I think I've watched the most and I think that would be "Lawrence of Arabia". I remember seeing a interview with Kevin Costner once and he talked about how one of his movies was a flawed movie (think it was waterworld) anyhow he went on to say most movies have at least some flaws. I don't think I have one single favorite movie of all-time but I think Lawrence of Arabia is as flawless a film as I've ever seen.
