Western Animation: The King and the Mockingbird

A classic French animated film (French title: Le Roi et l'oiseau), with one of the longest development times in animation history; even longer than The Thief and the Cobbler. Although the total amount of years is less when you consider that the film was made in two parts: 1948-1952 and 1977-1979, a total of 6 or so years.

It is considered a major inspiration by Hayao Miyazaki.
