Kingdom of the Sun (later titled Kingdom in the Sun) was the former version of The Emperor's New Groove before it was halted and drastically overhauled. The film would have originally been directed by Roger Allers with the intent to make the film an Incan epic follow up to The Lion King. The plot was more akin to The Prince and the Pauper with mystical elements and a musical. The story of its production history and its transition into the final film was chronicled in The Sweatbox.
