I remember the one about being a character best from The Color Of Money when Felson tells Vinnie that he is a character, an incredible flake. LOL
now, it's been awhile... but as I recall, it was nearing the end, when Harvey Keitel, (a.k.a., "The Wolf") tells John Travlogta & SAm Jackson: that 'you konw? maybe it was Q. T.

~but what he says to him, was: "Remember, just because you are a character. Does not necessarily mean, that you have, character..." ;D
