Input: Question: Who voiced the character Wolfgang animated in Peter Pan? Passage:Reitherman was hired at Walt Disney Productions on May 21, 1933, and his first project was working as an animator on the Silly Symphonies cartoon, Funny Little Bunnies. Reitherman continued to work on a number of Disney shorts, including The Band Concert, Music Land, and Elmer Elephant. He animated the Slave in the Magic Mirror in Snow White and the Seven Dwarfs (1937). His next assignments was animating Monstro in Pinocchio (1940), the climactic dinosaur fight in Igor Stravinsky's The Rite of Spring in Fantasia (1940), and several scenes of Timothy Q. Mouse in Dumbo (1941). Starting in 1942, Reitherman had left Disney to serve in World War II for the United States Air Force, earning the Distinguished Flying Cross after serving in Africa, China, India and the South Pacific. He was discharged in February 1946 having earned the rank of Major. Reitherman rejoined Disney in April 1947, where he animated the Headless Horseman chase in "The Legend of Sleepy Hollow" section in The Adventures of Ichabod and Mr. Toad (1949). Around this same time, he had claimed he was instrumental in helping Walt Disney commit to producing Cinderella (1950). Reitherman recalled, "I just went in his office which I rarely did, and I said, 'Gee, that looks great. We ought to do do it.' It might have been a little nudge to say, 'Hey, let's get going again and let's do a feature'." On Cinderella, he was the directing animator of the sequence in which Jaq and Gus laboriously push and pull the key up the stairs to Cinderella. On Alice in Wonderland (1951), he animated the scene in which the White Rabbit's home is destroyed by an enlarged Alice. On Peter Pan (1953), he animated the scene of Captain Hook attempting to escape the crocodile. For Lady and the Tramp (1955), Reitherman animated the alley dog fight sequence and Tramp's fight with the rat in the nursery room.
