Overview
A Snow White Christmas is a Christmas animated television special produced by Filmation and telecast December 19, 1980, on CBS. The special is a sequel to the fairy tale "Snow White", unrelated to Filmation's other sequel to "Snow White" titled Happily Ever After (1989), which ignores everything from this film.
The film's plot revolves around the return of the Wicked Queen, who is unexpectedly brought back to life during Christmas and casts an evil spell that freezes the entire land. Only the young Snow White, the daughter of the original Snow White, manages to escape and take refuge with seven friendly giants with her dwarf friend, but the Queen keeps trying to get rid of Snow White and her protectors. It is up to the giants to defeat her forever and save the kingdom.
Plot
After vanquishing the Wicked Queen, Queen Snow White and her husband King Charming are now the rulers of the land of Noel. They have a teenage daughter, also named Snow White for her snow-white hair. The royal family decides to host a Christmas Eve winter sports festival. One of the participants is Grunyon, a bumbling dwarf and a friend of the young Snow White. Princess Snow White says her Christmas wish is to build a playhouse for all the children and suggests remodeling the deserted castle on a mountaintop nearby that used to belong to the original Snow White's evil witch stepmother, the Wicked Queen, who has mysteriously disappeared when she was defeated.
Unknown to all, the Wicked Queen had been standing frozen near her abandoned castle all that time, and right then she is freed when it happens that the large block of ice in which she was trapped melts. Returning to her castle, the revived Queen finds her Magic Mirror still in place and learns that now are two Snow Whites more beautiful than her. Furious, she conjures a magical ice storm that freezes the entire kingdom but barely misses the second Snow White. The princess is told by her mother to find the Seven Dwarfs immediately before her parents are transformed into ice statues. Grunyon, who was also spared being frozen, leads Snow White into the forest to escape the storm. After finding their way into the Warm Valley, they accidentally wander upon a giant garden and two giants appear (Finicky and Corny) who mistake them for bugs and try to squash them.
