Or "The Fish Hammers". It's a new movie, French-Belgian production. I just went to the pre-premiere last night. :) Id provide a link, but it's not been published on imdb yet.
Anyway, the plot is rather simple - a professional jazz singer, and also a mother of a handicapped girl, is always on tour and much to busy to deal with her daughter, so she put her in a specialized center at a very young age. But when the mother is forced to spend a holiday with her daughter and the other people in the institution, she discovers many of them have a great music talent as well.
A few snapshots from the film.
So, a bit of a cliche, but it was really nice - especially because they didn't fake with the handicapped actors. I got invited by some friends, whose son (who's got Down's Syndrome) plays one of the people in the home. He probably had the smallest role but gave the biggest applause to himself :). After the show, they played some of the soundtrack. The pianist reminded me a lot of Dave Matthews' character on House - from what I gathered, he can play pretty much anything, but he can't start on his own.
Oh, and one more thing. The friend I was with, Laura, was sure she saw Sarah Palin somewhere in the audience, haha. She wouldn't let go of it, and kept stalking the woman aftewards. Needless to say the Senator didn't come to see a low-budget film all the way to Europe :)
