I would recommend
Amelie, which i thought was excellent,
Run Lola Run,
Das Experement, and i know a lot of people seem to like the Three colours movies, (
Blue,
Red and
White), but i havent seen them myself.
Then there is
Belleville Rendez Vous which is a animated feature but its quite funny and quirky as hell,
City of God (a very good movie) set in the slums of Brazil, and finally a couple of my favourites...
Battle Royale
and
Spirited Away
A couple of films i would definately recommend to anyone, although Battle Royale could be concidered an aquired taste, Spirtied Away is simply a Beautiful movie.
