Agreed in terms of how good this decade was overall.

1. 2001: A Space Odyssey (Stanley Kubrick / UK/US / 1968)
2. 8 1/2 (Federico Fellini / Italy / 1963)
3. Lawrence of Arabia (David Lean / UK/US / 1962)
4. Weekend (Jean Luc Godard / France/Italy / 1967)
5. La Dolce Vita (Federico Fellini / Italy / 1960)
6. Psycho (Alfred Hithcock / US / 1960)
7. The Manchurian Candidate (John Frankenheimmer / US / 1962)
8. Jules and Jim (Francois Truffaut / France / 1962)
9. The Good, the Bad, and the Ugly (Sergio Leone / Italy / 1966)
10. Romeo and Juliet (Franco Zeffereli / UK/Italy / 1968)

Tough to narrow it down, and the order can fluctuate, but such is always the case.
