"The Black Cauldron" is a 1985 animated fantasy film produced by Walt Disney Productions. It is based on the first two books of Lloyd Alexander's series, "The Chronicles of Prydain." The story follows a young pig-keeper named Taran who embarks on a quest to prevent the evil Horned King from using a magical cauldron to conquer the world. The film features a mix of traditional animation and dark themes, which was a departure from earlier Disney films. Despite its innovative approach, "The Black Cauldron" received mixed reviews and was a box office disappointment, leading to a reevaluation of Disney's animation style in subsequent years.
