Cannes 2011. They think it could be the film "Le Havre" (2011) by the Finnish director Aki Kaurismäki.
The story is about the people in the port town of Le Havre, France trying to help an immigrant refugee boy from Africa cross the Channel to England.
This film has a very strong similarity to the 2009 film by Philippe Lioret "Welcome" starring Vincent Lindon. It won the Audience Award at the COLCOA 2009. It was very good film.
I remember briefly the line "The boy is trying to cross the Channel to tell the girl how much he loves her, and I can't even do that to the girl in front of me.." (it wasn't exactly that, my memory is very vague) it was very touching.
I am not sure if the new film "Le Havre" will be any better, but the story has been around and already done.
The film "Welcome" (2009) is Highly Recommended.
