Prospero's Books is a complex tale based upon William Shakespeare's The Tempest. Miranda, the daughter of Prospero, an exiled magician, falls in love with Ferdinand, the son of his enemy; while the sorcerer's sprite, Ariel, convinces him to abandon revenge against the traitors from his earlier life. In the film, Prospero is Shakespeare himself, conceiving, designing, rehearsing, directing and performing the story's action as it unfolds and in the end, sitting down to write the completed work.
Ariel is played by four actors: three acrobats—a boy, an adolescent, and a youth—and a boy singer. Each represents a classical elemental.
