Talk about high society: This 1956 movie musical is the romantic comedy made by Grace Kelly after she had just become engaged to Prince Rainier of Monaco. Here, she’s one point of a romantic triangle, the other points being crooners Bing Crosby and Frank Sinatra. Sinatra plays the guy she intends to marry, and Crosby plays her ex-husband, who wants her back. Oh, and Louis Armstrong and his band are on hand throughout, making this even more valuable a movie musical.
