City of God. Won Cannes thingys.
Watched it last night (dvd from blockbuster), and although there are subtitles, it is simply a fantastic film.
Some bits are pretty grim and unpleasant, but the film is Full of action. It's an amazzing look into how some people live. (it's based on a true story)
It's based in Rio De Janero and is about this slum (or rather the people who live in the slum) where all the homeless people got sent.
