In the kingdom of Taronia, American banker Richard Gresham has a chance meeting with King Anatol XII at a mud bath. Anatol is searching for a solution to the country's economic woes. Gresham agrees to set up a $50 million bond loan, but he says the country needs to initiate a major public relations campaign in the United States to get enthusiastic backing. Anatol sends his daughter Princess Zizzi who is happy to leave the country for a while as she is engaged to Prince Nicholaus, a man she doesn't love. Upon her arrival in the States, shepherded by Gresham, Zizzi faints while being introduced to the press. Gresham says she is exhausted, but it turns out she has the mumps and can't travel. A small team of investigators is sent out on the streets of New York to hunt for a young woman who resembles Zizzi to take her place on the PR tour. Meanwhile, penniless actress Nancy Lane, who looks exactly like the princess, steals a sandwich from an automat. When she is accosted by two men, she thinks they're police but they are really Gresham's men. Gresham offers her $10,000 to pose as the princess for a month, and a bonus if she can pull off one extra twist. Newspaper publisher Porter Madison III has been running stories opposing the bond loan, so Nancy is expected to do some extracurricular work and charm Madison into backing the loan. The tour is a success as is Nancy's charm offensive with Porter. Meanwhile, complications pile up. An actor who knows Nancy recognizes her as Zizzi; Nancy's landlord suspects that Nancy has been kidnapped; the drippy Nicholaus shows up in the States, catches on to the ruse, and plants suspicions in Porter's mind. This being a forerunner to the screwball comedy genre, we know happy endings are in store.
Sylvia Sidney, not known for comedy, is the reason to watch this. She is charismatic and energetic in the dual role of Zizzi and Nancy (pictured above in both roles). Edward Arnold does a fine job as Gresham; given his persona in other films and the fact that he's playing a banker during the Depression, we might expect him to be unlikable (he tells Anatol, "We don't boast about being bankers these days; we're all in the doghouse!") but he's almost as appealing as Sidney. Reliable character actor Henry Stephenson is fun in the small role of the King (he does get to reappear briefly at the end) and Vince Barnett is fine as Nicholaus. The script is fairly solid and the repartee fun. The only minus is, surprisingly, Cary Grant as Porter. His character is one-dimensional—we don't even know why he is against the loan—and Grant seems uncomfortable in the role, never quite finding his footing. This was still early in his career, and he was apparently not happy to take the part in the first place and I think that shows a bit. There is a very amusing scene at a party where a slightly drunken Sidney starts toasting the past kings of Taronia, leading the partygoers to smash drinking glasses with each toast. An amusing trifle which Sidney makes worth watching. [TCM]
