Annie Hall
Casablanca
A good amount of the AFI Top 100:
The top ten:
1. "Citizen Kane," 1941
2. "Casablanca," 1942
3. "The Godfather," 1972
4. "Gone With the Wind," 1939
5. "Lawrence of Arabia," 1962
6. "The Wizard of Oz," 1939
7. "The Graduate," 1967
8. "On the Waterfront," 1954
9. "Schindler's List," 1993
10. "Singin' in the Rain," 1952
I've only seen Kane, Godfather, Oz (Don't remember it tho), and Schindler's List.
Could make it into a poll.
Give yourself a check and see how many you have seen.
