"Kingdom of the Sun" was to have been a tale of a greedy, selfish emperor (voiced by David Spade) who finds a peasant (voiced by Owen Wilson) who looks just like him; the emperor swaps places with the peasant to escape his boring life and have fun, much as in author Mark Twain's archetypal novel "The Prince and the Pauper". However, the villainous witch Yzma has plans to summon Supay (the evil god of death), and destroy the sun so that she may become young and beautiful forever (the sun gives her wrinkles, so she surmises that living in a world of darkness would prevent her from aging). Discovering the switch between the prince and the peasant, Yzma turns the real emperor into a llama and threatens to reveal the pauper's identity unless he obeys her. During his time as the emperor and doing Yzma's orders, the pauper falls in love with the emperor's soon to be fiancé Nina who thinks he is the emperor that has changed his ways. Meanwhile, the emperor-llama learns humility in his new form and even comes to love a female llama-herder named Mata (voiced by Laura Prepon). Together, the girl and the llama set out to undo the witch's plans. The book "Reel Views 2" says the film would have been a "romantic comedy musical in the 'traditional' Disney style".
