Not sure what my list would be (would most likely include The Matrix, The Gladiator, and Braveheart for sure), but these would be in contention for many people (trying not to repeat any that others have already mentioned):
- Ben-Hur (1959)
- The Sound of Music (1965)
- Fiddler on the Roof (1971)
- Blade Runner (1982)
- The Silence of the Lambs (1991)
- Braveheart (1995)
Oh, and probably need something of Eastwood's in the list - one of the westerns, Dirty Harry, or modern films.
