Modern sources include in this film the songs "Marianne," Funny Little Sailor Man" and "Softly, as in a Morning Sunrise" (all from the original stage production), but they were not heard.
Some production charts included Hale Hamilton and Marie Mosquini in the cast, but they were not seen in the movie.
The operetta, "The New Moon," opened on Broadway in New York City, New York, USA on 19 September 1928 and closed on 14 December 1929 after 509 performances. The leads were played by Robert Halliday and Evelyn Herbert, and the supporting cast included Gus Shy, who is also in this movie.
When first sold to television in 1957, this film was retitled Parisian Belle in order to avoid confusion with _New Moon_ (1940), which was also in the same package of over 700 MGM titles. However, whereas Parisian Belle would have been an appropriate title for the 1940 version, which followed more closely the original story, it was a misnomer for this 1930 version whose locale had been moved to Russia, and whose heroine, the Parisian Belle of the stage play and 1940 version, had now become a Russian princess. But it was so seldom broadcast at that time that nobody seemed to notice or care.
