The Court Jester movie

The throne of rightful king of England, the small babe with the purple pimpernel birthmark, has been usurped by the evil King Roderick. Only the Black Fox can restore the true king to the throne—and all he needs is the kings key to a secret tunnel. And while hes trying to steal it, someone has to change the kings diapers. The task falls to Hawkins, the gentlest member of the Foxs band. The Foxs lieutenant, Maid Jean, guards Hawkins and the babe while they travel, but when they meet the Kings new jester on the road, they decide to initiate a daring plan for Hawkins to replace him, become an intimate at the court, and steal the key. So, humble Hawkins becomes Giacomo: the king of jesters and jester to the king. But things begin to get zany when the Kings daughter falls for Giacomo, the King falls for Jean, people randomly sing what are supposed to be recognition codes, and a witch with very effective spells (and poison pellets) begins to interfere.
