I grew up watching many Serbian films, as I was born there, my favourites being Kusuturica's stuff, Underground, Zivot Je Cudo, Dom Za Vesanje, Crna Macka Beli Macor, Sjecas Li Se Dolly Bell, and so on, but I also enjoy the classics like Ko To Tamo Peva, Maratonci Trce Pocasni Krug, etc.
other foreign films I like are
City Of God (Brazil) <-----one of the best foreign films ever imo
Amelie (France)
The Gods Must Be Crazy (South Africa)
Pan's Labyrinth (forgot where that was from lol, Spain?)
