off the top of my head,
apart from the top 3, the rest are in no particular order.
1.Casablanca
2.In the Mood for Love
3. Brief Encounter
The United States of Leland
Witness for the prosecution
Notorious
Vanilla Sky
Stay
Paradise Now
Old Boy
there are some better ones, but i can't remember them right now.
it is hard to make a top 10 list, since there are so many films out there that are deserving, ok...maybe not that many, but i guess it depends how i feel at the moment, the top 3 are there, but the rest are interchangeable with other films.
