Disney decides to go all out with a film that still defies all expectations in FANTASIA (1940). Each segment is worth a deep dive (even one that doesn't delight us), but we explain why the whole project is a triumph of curiosity and musical brilliance. We also talk to Oscar-winning filmmaker, animator, historian, and author John Canemaker about why he is in awe of the technical mastery of Fantasia, why everyone is an artist, and how Mickey Mouse gives his greatest performance to date.
