That list makes me feel uncultured only watched 12 movies on that list Citizen Kane, Casablanca, Star Wars, Chinatown, One Flew Over the Cuckoo's Nest, Mr. Smith Goes to Washington, To Kill a Mockingbird, Double Indemnity (one of my favorite movies!), Fantasia, Raiders of the Lost Ark, Forrest Gump, My Fair Lady. Looks like I need to rent more...
You probably just don't watch a lot of old movies. I think I've seen just about everye, except Chaplin's Modern Times, which was released in the '30's and was one of the last silent movies. I have to rent it now.
I bet if we could have a great discussion about the best baseball movies of all time. Mine is probably Bull Durham, though I detest Costner.
