I will try to stifle the urge to continually add to my list but can't leave out these, starting with two recent favorites directed by Clint Eastwood and the one that made him famous --

Mystic River
Million Dollar Baby
Dirty Harry
Amelie
Almost Famous
Diva
The 400 Blows
Breathless
Speed
The Friends of Eddie Coyle
The French Connection
The Ice Storm
Die Hard (my favorite Christmas movie)
Heat

There are about a hundred more. Now you've made me want to rewatch all of them....
