Well done adaptation of the beginning parts of "The Once and a Future King". The sequences when Merlin is training Arthur by changing him in to animals are terrific.
Leonard Maltin/Plot synopsis:
One of Disney's weakest animated features follows a young boy named Wart, who is destined to become King Arthur--with the considerable help of Merlin the Magician. Mildly entertaining and fast-moving, but dialogue-heavy, and full of "modern" references that remove much of the magic and wonder from T. H. White's story. Highlight: wizard's duel between Merlin and Madame Mim.
