Maybe it's this one?
I've been looking for a similar one (if not the same one) also. My mother grew up in Finland, and she always said that Finnish filmakers had made some very good movies when she was young. I've always wanted to see one. She mentioned Sleeping Beauty, and a Beauty and the Beast, but she wasn't sure if Beauty and the Beast was actually Finnish or not.
I can't find it anywhere either really. It seems that people will play the movie periodically on Youtube as a live stream. Since that's the case, you can only watch it when someone is streaming it
