Royal Wedding is a 1951 American musical comedy film directed by Stanley Donen and starring Fred Astaire and Jane Powell, with music by Burton Lane and lyrics by Alan Jay Lerner. Set in 1947 London at the time of the wedding of Princess Elizabeth and Philip Mountbatten, the film follows an American brother-sister song-and-dance duo, each of whom falls in love—the brother with a female dancer and the sister with an impoverished but well-connected nobleman. The film marked Donen's second directorial feature. It was released as Wedding Bells in the United Kingdom.
