Although Faith Baldwin is credited onscreen as writer of a novel, it was actually just a short story in a magazine. No novel was ever published.
Based on the short story "Spinster Dinner" by Faith Baldwin published in Heart's International-Cosmopolitan magazine in the July, 1934 issue.
The image of Carole Lombard with a prominent black eye - which today would be considered "utterly un-P.C." - was used in almost all promotional materials for this film. Curiously, the posters and print ads show Lombard with her black eye on the left, yet in the film it's her right eye that takes the mis-directed punch.
At one point, Melvyn Douglas was cast in the male lead role, which eventually went to Preston Foster.
Lester Dorr (Attendant), Earl Eby (Entertainer) and Robert McKenzie are in studio records/casting call lists as actors in this movie but they never appeared. Eby may have been the pianist at Dubin's, but he is never shown. Bert Roach is listed as "The Host" in the onscreen credits and may possibly be seen in long-shot in one of the party scenes, but for all practical purposes he was deleted from the final print. Some of the other actors can be briefly seen but have no lines. There may have been extensive editing, since it is listed in studio records as an 8-reel production, but only runs 70 minutes.
