I saw this movie around 2011-12 on tv but movie was probably older than these dates, i only vaguely remember it but for some reason i got curious about it recently.
It was about bunch of little girls learning ballet, or something similar in a camp in the woods, isolated from rest of the world. There were only teachers and the little girls in the camp. At the end of the movie children were taken to a city where they perform their dance, not on a theatre but infront of some building during middle of the day while rest of the people were passing by and minding their own business.
I think it was a arthouse movie, definitely not a comedy or action.
