12 monkeys is epic to, good one. Black cat white cat is a kusturica movie, gypsy stuff but funny.
Yeah city of god is a good one.

Also this one is pretty intresting:
Skritek ( don't look for subtile, no talking, just sounds )
Las brujas de zugarramundi ( nice director and nice movie )
Irreversible
Kontrol
Taxidermia
Memento
Carandiru
And i've see a nice horror comedy lately. Dead Snow. It was a nice one. Nordic films are always good.
I'll come up with more if u guys want to.
