The Prince and the Showgirl (1957)

Among the dignitaries from the Balkan State of Carpathia in London for the coronation of King George V and Queen Mary in June 1911 is the Regent, His Serene Highness the Grand Duke Charles. The London foreign office places great importance on Carpathia because of an unstable geopolitical situation with Kaiser Wilhelm of Germany set to overthrow its monarchy government if allowed. The Regent, a Prince originally from Hungary, and the most-recent, now-deceased Queen married for convenience. As such, the Regent has spent time with a series of lady friends while on his travels in his somewhat "free" state. In meeting one of those London women, music-hall actress Maisie Springfield, and the company of her current production "The Coconut Girl," the Regent has his eye on one of the show's minor players, American actress Elsie Marina. When seemingly-simpleminded Elsie receives a party invitation instead has his eyes set on one of the minor players in the show, American actress Elsie Marina. When seemingly simpleminded Elsie receives a party invitation from the Regent for that evening, she clearly understands the implications when she learns upon her arrival at the Carpathian Embassy, where the Regent and the Carpathian entourage are staying, that the party is just for two.
