According to her autobiography, Myrna Loy was originally going to wear white empire-style dress for the party sequence, but Jeanette MacDonald was jealous of how she looked insisted that she had to wear it herself instead. Loy surrendered the dress, but then went down the to the costume room and, with a friend's help, put together the black lace outfit she wears in the final film. She stole the scene.
MPAA/PCA files at the AMPAS Library reveal that while most of the songs in the film were approved prior to release, the Hays Office objected to the suggestive nature of the song, "A Woman Needs Something Like That," although it was left in the film. Jesse Lasky, Jr. responded in a letter to the MPPDA's concern about the line "Must we sleep tonight all alone?" in the song "Love Me Tonight," by noting that the line had been changed to "Let's drink deep tonight all alone."

In addition, Didot maintained that as long as the duke and princess were not implied to have royal blood, the film should not give offense. The film was rejected in Czechoslovakia, approved without eliminations in Quebec, New York and Kansas, and approved with eliminations in Australia, Britain, Chicago, Ontario, British Columbia, Ohio, Alberta, Pennsylvania and Massachusetts.

According to a memo in the file, the four-reel re-release was unsuccessful
