A while ago, kottle.org posted a list of the 100 movies you should have seen to consider yourself movie literate (acc. to Jim Emerson):
"...they [are] the movies you just kind of figure everybody ought to have seen in order to have any sort of informed discussion about movies. They're the common cultural currency of our time, the basic cinematic texts that everyone should know, at minimum, to be somewhat "movie-literate."

That's only 38. Pathetic. Although there a few that I've seen in enough 30 minutes chunks that in theory I could count them including Godfather, Chinatown, Bonnie and Clyde, etc. And then I've seen other films by the people that made these films like Mr. Smith Goes to Washington, You Can't Take it With You, City Lights, etc. But seriously I'm ashamed of myself. How can I have not seen Godfather 2, It's a Wonderful Life, Casablanca, Taxi Driver, On the Waterfront, etc, etc, etc. I'm almost too ashamed to post this.
