This film was based on a very successful Broadway musical which ran for nearly 350 performances, but even the score by Kern & Hammerstein couldn't save the film. Its hit song, "I've Told Ev'ry Little Star," is still recognizable today.
I can't blame the actors, even though the ensemble might have been better-cast. Only one lead actor, Al Shean as Dr. Walter Lessing, was carried over from the play to the film, and one minor (non-speaking in the film), Marjorie Main as Frieda's maid, Anna. All were very good in their roles, but they didn't all "click" together, so I have nobody to blame but the script adapters and/or the directors, both main and casting (whoever the latter may have been).
This was one of nine John Boles films made that year. (Wow!) Gloria Swanson was a silent film star, but not one of several who failed the transition into sound films. As evidenced by her performance here, she not only spoke well, but she also had a fine singing voice. Nevertheless, after about a half dozen sound films, this was her last film for seven more years, and then another nine before her classic, "Sunset Boulevard," which earned her a Golden Globe for Best Actress. "Sunset Boulevard" also earned her her third Oscar nomination for Best Actress, but she lost out on all three to others.
