Italian for "King of Everything
The self-proclaimed title of the Man in the Moon in The Adventures of Baron Munchausen.
Some interesting trivia: the above-mentioned character was originally to be played by Sean Connery (which many feel would have ruined an otherwise scene-stealing cameo.) At the last minute (over protest of cutting of Gilliam's budget) he backed out and Robin Williams assumed the role of this bipolar (well, deeply divided) character.
Williams is uncredited as the list of names scrolls by at the conclusion of the movie, but if you look carefully you can see that the role of King of the Moon is played by Ray D. Tutto.
