The Polar Bear King 1991
After his father is killed, King Valemon ascends the throne, only to be turned into a polar bear by a bitter witch who wants to be his queen. Valemon must find a bride in the seven year span that he’ll be a polar bear, and so he travels to Winterland and finds a wife to take home. Although they are happy, she is not allowed to look upon his face when he turns back into a man at night. When she breaks this rule, Valemon will be trapped to the witch forever.
