I'm looking for a cartoon movie I can't rememeber exactly what its about but I do remember a scene where this young boy is running away from this witch. She is flying above him in the sky and when she spreads out her arms she brings with her the night skies all dark and full of stars.The darkness in her path has 2 different shades of night to them as well. As the boy keeps running she follows and has to defeat her. I know I watched it in the mid 80's any suggestions
