Robin Williams' flamboyant appearance as the King of the Moon was concealed behind the credit 'Ray D. Tutto,' an Italian pun meaning roughly 'king of everything.' The disguise was not a whimsical marketing stunt invented by Gilliam: according to the director, Williams's agents objected to the film using the actor's name to promote itself, reportedly saying they did not want the production 'pimping his ass.' As a result, audiences could watch Williams play the moon monarch—a bizarre being whose head and body possess separate minds—without seeing the star's real name in the credits. The alias became one of the production's oddest pieces of lore, especially because Williams was instantly recognizable and his performance was one of the film's most conspicuous comic attractions. Gilliam later explained the arrangement directly, making the story a documented example of star-management politics and credit control rather than an urban legend. Williams was eventually listed in later accounts as the performer behind Ray D. Tutto, while the name itself remained a private joke embedded in the film's already extravagant mythology.
