Based on the novel by T.H. White, The Sword in the Stone (also known in some places as Merlin the Magician) is Walt Disney's 18 animated feature.
It was the last film in which Bill Peet would work as a writer. Peet, who had worked for Disney as a writer and character designer would leave the studio just before the production of The Jungle Book (his original screenplay was scrapped) when his relationship with Walt started falling apart.
But it would eventually be the last feature that Walt would see completed. Although he was very active in the production of this movie, Walt would never be able to see it screened in theatres. Due to lung cancer, he died just a year before The Jungle Book's release.
Walt's brother Roy would take over Walt Disney Productions .
