No child should be denied the experience of watching this landmark film. The highlight of “Fantasia” for many audiences is “The Sorcerer’s Apprentice,” starring Mickey Mouse as a lowly magician’s assistant who dreams of wielding great power over the waters of the ocean and gets carried away. Tchaikovsky’s “The Nutcracker Suite” is a colorful treat, as dancing mushrooms and thistles frolic to his famous themes. Stravinsky’s “Rite of Spring” becomes an accompaniment to the roaming of dinosaurs. “The Dance of the Hours” is a delightful ballet performed by hippos, alligators, and ostriches. And “Night on Bald Mountain” is a fearsome display of evil during a night of devilry. There has never been another film quite like this one.
