In this swashbuckling comic farce, star Danny Kaye is kind-hearted entertainer Hawkins who disguises himself as the legendary king of jesters, Giacomo. Hawkins infiltrates the court of an evil villain (Basil Rathbone), but when a sorceress hypnotises him, royal chaos ensues. Alternating identities at the snap of a finger, between swordplay and wordplay, Kaye's comic genius shines through. The stellar supporting cast includes Glynis Johns, Angela Lansbury, Mildred Natwick, Cecil Parker, and John Carradine.
