Here is a list of the all time best quotes from film characters. This was the ballot the American Film Institute used to put together tonight's special on CBS.
Reading this reminds me of one of the best TV ad campaigns I ever saw. One of the Turner networks was debuting "movies for guys who really like movies" about 10 years ago. The commercials featured nondescript guys approaching strangers and reciting lines that everyone knew (like "Hasta la vista, baby"). The best part were the ones that were more obscure (like "I'm an excellent driver" - I haven't TIVOd the show yet so I can't tell if that one made the top 100, but it is number 290 on the ballot).
