Can you recommend me some movies based on...?

I watched a brilliant Korean movie based on the fairytale Hansel & Gretel, it was quite dark and weird, very surreal! It was called "Hansel & Gretel" (funnily enough!) but if you don't mind subtitles, I think you'd enjoy it. You could also try the Spanish movie "Pan's Labyrinth" it's a beautiful movie, full of mystery and fantasy and great imagery.
