After making this movie, David Niven returned to England to serve in the British Army during World War II. At the Battle of the Bulge in 1944, German infiltrators into American lines caused roadblocks to be established and military police asked all suspicious persons questions about things no German was likely to know. Lt. Col. David Niven was stopped at a roadblock and was asked who won the baseball World Series in 1940. He replied, "I haven't the faintest idea, but I do know that I made a picture with Ginger Rogers in 1938." The MP replied, "OK, beat it, Dave, but watch your step, for Chrissake."
During the Times Square New Year's Eve festivities, a marquee for the movie "Love Affair," starring Irene Dunne and Charles Boyer, is in the background. It, too, was released in 1939 by RKO.
Ginger Rogers and David Niven would go on to co-star in La primera dama (1946) and ¡Qué hombres, qué mujeres! (1957). Coincidentally, both stars won an Academy Award from only receiving one nomination each during their entire careers.

The quacking Donald Duck toys featured prominently in this film are probably because RKO once distributed Disney's films.
