So, Ivo Caprino was this Norwegian doll and film-maker, that held his secrets close to his chest for almost his whole life.
I grew up with my father always saying "nobody knows how he does it!". Now the doing it is referring to how he gave his dolls life. Nobody could figure it out, and it added a whole lot of mystery to the whole thing.
Now we know, and the system he invented is pretty neat. Forget it! I won't tell you! It's a secret, for crying out loud! ;)
So. Ivo Caprino produced a whole lot of movies, among them several that were based on well known fairy tales. They are pretty much all great.
And this one is no exception. The animation is excellent, and has a super distinct look, that makes you know this is Caprino handy-work. Great.
