Definitely in the top five. My top ten:
10. Lawrence of Arabia
9. Psycho
8. The Great Dictator
7. Once Upon A Time In The West
6. Blade Runner
5. Dr. Strangelove
4. Citizen Kane
3. It’s A Wonderful Life
2. The Godfather
1. Casablanca (and it’s not terribly close)
Charlie Chaplin’s talkie is in your top 10? Who woulda thunk? (was that his only talking film? I think so... )
