Sito assisted retired Disney animator Shamus Culhane on one of his final projects, a 1977 education short entitled Protection in the Nuclear Age. Tom Sito was summoned by his old mentor Richard Williams in 1987 to animate on Disney/Amblin's Academy Award-winning hit film Who Framed Roger Rabbit?. Returning to Los Angeles in 1988, Sito became a mainstay of the Disney Feature Animation division, contributing to the classic films The Little Mermaid, Beauty and the Beast, Aladdin, The Lion King, Pocahontas, Fantasia 2000, and Dinosaur. In 2010, Tom Sito was awarded the June Foray Award at ASIFA-Hollywood's Annie Awards for a lifetime of service to the animation community.
