Don’t be misled by the title – though MGM probably hoped people would be. There is nothing very glitzy about this movie, not all that much pageantry, and the only “king” featured is Fred Astaire in a pasteboard crown for the opening musical number.
For the most part, the royal wedding, of Princess Elizabeth and Prince Philip, is just a backdrop, and the film was released as Wedding Bells in the UK to make it clear the royals didn’t actually feature. The main story is an amusing and occasionally poignant backstager partly based on Astaire’s own early career, when he and sister Adele were famous dancing partners until she retired from the stage to marry a British aristocrat. However, the story is probably secondary to the stunning dance numbers, including the famous one where he dances up the walls and around the ceiling. Jane Powell ‘s beautiful singing voice is another definite plus to this movie, which has songs by Alan Jay Lerner and Burton Lane and a screenplay by Lerner.
