My favorite classics (pre-1970) are
1. 12 Angry Men (1957)
2. Witness for the Prosecution (1957)
3. Dial M for Murder (1954)
4. North by Northwest (1959)
5. Gone with the Wind (1939)
6. Arsenic and Old Lace (1944)
7. All About Eve (1950)
8. Wizard of Oz (1939)
9. Harvey (1950)
10. Sunrise (1927)
As great as 1939 was for movies, the decade of the 1950s had the best movies.
