Film: 'Ali Zaoua, Prince de la Rue'

I'm not really into films, but I came across this Morroccan film on BBC2 the other day that managed to keep me interested right till the end. It was about three glue-sniffing kids on the streets of Casablanca, trying to give their friend and leader Ali Zaoua a burial fit for a prince.
The plot was difficult and upsetting, but the characters had so much depth it was hard to remain detached from the emotions they were going through. And the imagery of the symbols of beauty that were dropped in alongside the harshness of these children's existence was really thought-provoking. I still can't get over how good the acting was, none of them seemed more than 10 years old.
It is sad to think that people might be living like the kids portrayed in the film, yet it probably happens in many places all over the world.
