In order to avoid the inevitable unhappy ending (Grace Moore died in an airplane crash in Copenhagen in January 1947), WB chose to end the story nearly 20 years earlier, which those who knew her, and her fans who still fondly remembered and loved her, felt was a cop-out. At the time of her death, she had most recently gained renewed popularity entertaining the troops around the world during World War II on behalf of the USO.
The film ends with Grace Moore's successful debut at the Metropolitan in 1928; no mention is made of the fact that, during the next ten years, she went to Hollywood and made a number of major films, beginning at MGM in 1930, and later, more successfully at Columbia, beginning with One Night of Love in 1934 (for which she received an Academy Award nomination.) She never appeared before the camera for Warner Bros. who made this film.
"Marilyn Montgomery" (as portrayed by Marie Windsor) was a thinly disguised Marilyn Miller, whom WB had recently whitewashed in another recent screen biography, Look for the Silver Lining (1949) and whose image they did not wish to sully so soon afterwards.
As part of this film's promotion, new Warner Brothers star Merv Griffin was sent on an all expenses paid promotional tour of major cities across the U.S. At his stop in Boston, he found out that Freddy Martin and his orchestra, for whom Griffin had been the lead singer, were in town doing concerts, so Merv invited the whole group to his suite at the Statler Hotel for a champagne and caviar reception. When studio head Jack Warner saw the hotel bill - more than $3,000 just for the food (at a time when $3,000 was enough to buy at least two brand new automobiles) - Warner was furious.
