I'm looking for this movie, but I barely remember it. It seemed to be from the 2000's and I'm not sure but I think it wasn't in English.
It was a very cute film, about an ageing Soviet composer (maybe Russian? Or German? Don't remember) that had written some ballet or orchestral piece that never got to be played, or maybe he was censored back in the day, and being now in a democratic country he was somehow convinced (maybe by a female love interest?) to finish the piece and... they gather an orchestra and all of the players are old people that used to play for this composer many years ago. And they get to play to some big, renowned theatre and the composer finally gains recognition and respect. Oh and I think the composer and the musicians travelled in a ratty old van, maybe a Volkswagen Camper or something similar, along with all their instruments.
