Hmmm. I could never narrow it down to 10. That list would change any time I tried to recite it. Here is a feeble attempt:
1. The Music Man (1962; Robert Preston, Shirley Jones)
2. To Kill a Mockingbird (1962; Gregory Peck)
3. The Thin Red Line ('60's; Kier Dullea)
4. QB IV (1973?; Anthony Hopkins)
5. The Cowboys (1972, John Wayne)
6. Elmer Gantry (1960; Burt Lancaster)
7. Where Eagles Dare (1969; Clint Eastwood, Richard Burton)
8. The Sting (1973; Paul Newman, Robert Redford)
9. Hud (1963; Paul Newman)
10. Man's Favorite Sport (1964; Rock Hudson)
If you ask me tomorrow, I might give this list:
1. Grand Prix (1966; James Garner)
2. It's a Mad, Mad, Mad, Mad World (1963; Spencer Tracy)
3. It's a Wonderful Life (1946; James Stewart)
4. Nevada Smith (1965; Steve McQueen)
5. Top Hat (1934; Fred Astaire)
6. Girl Happy (1965; Elvis Presley)
7. Catch-22 (1970; Alan Arkin)
8. Dr. Strangelove (1964; Peter Sellers)
9. The Learning Tree (1969; actor unknown, written by Gordon Parks)
10. Three in the Attic (1968; Yvette Mimieux)
My lists are pitiful. Humphrey Bogart does not appear. What about the African Queen, or Casablanca? Gary Cooper did not appear. Epic movies are not listed, such as Gone with the Wind and Ten Commandments.
It is impossible.
