Disney's "Nine Old Men", the animators responsible for Disney's most famous earlier works, and their associates began to hand their traditions down to a new generation of Disney animators. New faces such as Glen Keane, Ron Clements, John Musker, Andreas Deja, and others came to the studio in the late 1970s and early 1980s, a period that produced such features as "The Rescuers", "Pete's Dragon" (a live-action/animation hybrid), and "The Fox and the Hound", as well as the featurettes "The Small One" (Bluth's only Disney-directed credit) and "Mickey's Christmas Carol" (the first screen appearance of Mickey Mouse since 1953).
