Witches' Sabbath (1984)

To celebrate Sleeping Beauty's awakening, the cruel stepmother organises a dress-ball in the Wonder Castle and invites the characters of all tales and their two fathers, the Grimm-brothers. The stepmother announces total peace, but in fact she is preparing for a coup d'état with a phoney prince, a phoney Sleeping Beauty, through intrigue and violence in order to change the tales.
