A CHRISTMAS PRINCE: THE ROYAL BABY (2019) Stream on Netflix. “When Prince Richard (Ben Lamb) went to New York to ask the New York commoner and ‘journalist’ Amber (Rose McIver) to marry him in the first movie, I let out a high-pitched squeal,” Kaly Soto wrote of “A Christmas Prince” in her Times review of its sequel, “A Christmas Prince: The Royal Wedding.” Since Amber first visited the country, Aldovia, to interview its prince, the couple have been married, and are now expecting a tiny heir to the throne in “A Christmas Prince: The Royal Baby.” Complications arise, of course, when a treaty between Aldovia and another country is stolen just before Amber and Prince Richard are to sign it. If the treaty is not renewed, the royal baby will be cursed. All hands are on deck to save the royal baby in the third part of this trilogy where, apparently, it is always Christmastime.
