Saint Ralph... I just feel inspired every time I watch that, even though I'm atheist. It's just such an uplifting, perfect movie in my opinion.
La Vie en Rose
Downfall
Forgot those two.
Downfall has brilliant acting.
The Beast,
A fantastic story about the war in Afghanistan during the 1980s.

Pan's Labyrinth
Down with Love (yes, I tend to like Ewan McGregor movies)
Is Downfall/Der Untergang underappreciated? Maybe I just hang around with people who like that sort of thing but all my buds loved that film.
