The King on Main Street (1925)

King Serge IV of Molvania (Menjou) comes to Manhattan to conduct business with Arthur Trent (Kilgour), but instead goes to Coney Island, where he meets Gladys Humphreys (Love) and John Rockland (Shaw). John, not knowing the king's royal identity, invites him to his home at Little Falls, New Jersey. The king falls in love with Gladys, but Trent catches them in a compromising situation, and blackmails the king into completing their business deal. The king leaves the United States and Gladys forever.
