More burdened with leaden production numbers than plot, Rosalie took Sigmund Romberg and George Gershwin's 1928 Broadway hit, threw out most of the songs, including "How Long Has This Been Going On?," but retained the spindly story of the incognito Princess Rosalie of Romanza (Eleanor Powell), who falls head-over-heels in love with All-American Dick Thorpe (Nelson Eddy), although she finds him conceited at first. But Dick gallantly flies to Romanza where the crooning Charles Lindbergh lands in the middle of yet another comic opera revolution. Rosalie, of course, is engaged to someone else, but after a series of misadventures and a colossal closing number, the star-crossed lovers decide to settle down together in democratic America. Cole Porter was hired to write a new score and Eleanor Powell, Nelson Eddy, and newcomer Ilona Massey perform "I've Got a Strange New Rhythm in My Heart," "Why Should I Care?," "Spring Love is in the Air," "It's all Over but the Shouting," "Who Knows?," "To Love and Not to Love," and, most memorably, "In the Still of the Night."
