This isn't usually counted as being one of the top-ranking Disney films, but I insist on not being snobbish in this list, and remembering the films that brought me joy as a kid. Wart gets to be a squirrel, a bird and a fish during this film which plays fast and loose with Arthurian legend. Merlin is great, and his battle with Madam Mim the stuff of legend. It's not big, it's not clever, but it is fun!
