Brown), her grandmother Aggie (Debbie Reynolds), and her family of witches in this latest chapter in the ever-popular series of Halloweentown movies.

He's determined to destroy all things magical, and it's up to Marnie to save her high school, the human world, and her magic. For a bewitching good time, Halloweentown High is the perfect treat.
