Two real-life events were incorporated into the plot of the 1951 MGM musical Royal Wedding. One, the marriage of Fred Astaire’s sister Adele to a British nobleman had occurred years earlier; the other, the wedding of England’s Princess Elizabeth and Prince Philip was only four years in the past. The plot has Astaire and Powell heading to Merrie Olde England to perform at the palace. Once they’ve arrived, Powell breaks up the act when she falls in love with blueblooded Peter Lawford. Astaire himself finds romance in the form of Sarah Churchill (daughter of Sir Winston), and the four happy campers gleefully attend the titular Windsor Castle wedding. Also in the cast is Albert Sharpe, fresh from his Broadway triumph in Finian’s Rainbow, and Keenan Wynn, hilarious as twin cousins.
