Tytla is generally considered to be one of the greatest animators ever to work at the studio (Frank Thomas and Ollie Johnston once said that there would never be an animator to replace him), and the first to give animated characters emotions. On Snow White and the Seven Dwarfs he and Fred Moore were put in charge of the animation of the seven dwarfs. Tytla focused particularly on Doc and Grumpy; he animated Grumpy's reaction to a kiss from Snow White. He went on to animate three of Disney's most imposing, powerful characters: Stromboli in Pinocchio and Yen Sid and Chernabog in Fantasia, before moving on to the rather more sympathetic titular character of Dumbo.
