The King and the Mockingbird

The King and the Mockingbird (French: Le Roi et l'Oiseau, lit. 'The King and the Bird') is an animated fantasy film directed by Paul Grimault. Prior to 2013, it was released in English as The King and Mister Bird. Begun in 1948 as La Bergère et le Ramoneur (lit. "The shepherdess and the chimney sweep", loosely based on the fairy-tale of the same name by Hans Christian Andersen), the film was a collaboration between Grimault and popular French poet and screenwriter Jacques Prévert. However, the film suddenly stopped production and was released unfinished by its producer in 1952, without the approval of either Grimault or Prévert. Through the course of the 1960s and 1970s, Grimault obtained the rights to the film and was able to complete a new version as they originally intended. The film was completed over 30 years after production commenced.
