What was the last movie Walt Disney was able to work on before he died?

Walter Elias Disney was an American entrepreneur, animator, writer, voice actor and film producer (lifespan December 5, 1901 – December 15, 1966). A pioneer of the American animation industry, he introduced several developments in the production of cartoons. As a film producer, Disney holds the record for most Academy Awards earned by an individual, having won 22 Oscars from 59 nominations. He was presented with two Golden Globe Special Achievement Awards and an Emmy Award, among other honors. Several of his films are included in the National Film Registry by the Library of Congress.

"The Jungle Book" is a Walt Disney Productions American animated musical comedy film released in 1967. Based on the 1894 book of the same name by Rudyard Kipling, it is the 19th Disney animated feature film. Directed by Wolfgang Reitherman, it was the last film to be produced by Walt Disney, who died during its production.

As his friends Bagheera the panther and Baloo the bear attempt to persuade him to leave the jungle before the wicked tiger Shere Khan appears, the story follows Mowgli, a wild boy raised by wolves in the Indian jungle.

The early versions of both the screenplay and the soundtrack followed Kipling's work more closely, with a dramatic, dark, and sinister tone which Disney did not want in his family film, leading to writer Bill Peet and songwriter Terry Gilkyson being replaced.
