When Charles Coburn is trying to play Cupid between Irene Dunne and Charles Boyer (at 43 minutes), the musical motif is the tune from "Damn the Torpedoes, Full Speed Ahead" - the song Coburn hums and sings throughout "The More the Merrier" (1943), for which he won an Oscar for playing Cupid between Jean Arthur and Joel McCrea.
The elevator operator was played by Carl Switzer, best known as Alfalfa of The Little Rascals "Our Gang" fame.
Third and final film to pair Irene Dunne and Charles Boyer, after Love Affair (1939) and When Tomorrow Comes (1939). Even the title seems to reflect the fact that the actors are starring together again, and is not significantly related to the plot of the film.
