Broadway Rhythm (1944) is a Metro-Goldwyn-Mayer Technicolor musical film, produced by Jack Cummings and directed by Roy Del Ruth. It was originally announced as Broadway Melody of 1944 to follow MGM's Broadway Melody films of 1929, 1936, 1938, and 1940. It was originally slated to star Eleanor Powell and Gene Kelly, but Louis B. Mayer and MGM loaned Kelly out to Columbia to play opposite Rita Hayworth in Cover Girl (1944). The film instead starred George Murphy, who had appeared in Broadway Melody of 1938 and Broadway Melody of 1940. Mayer then replaced Powell with Ginny Simms. Other cast members included Charles Winninger, Gloria DeHaven, Lena Horne, Nancy Walker, Eddie "Rochester" Anderson, the Ross Sisters, and Ben Blue, as well as Tommy Dorsey and his orchestra.
