"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie on
May 5, 1941 with Ginger Rogers, Dennis Morgan and James Craig reprising their film roles.
Ginger Rogers was initially reluctant to take on the lead role, as the novel the film was based on contained explicit sexuality and Kitty has an abortion in it. Rogers' mother advised her to wait until she sees a screenplay before making up her mind, pointing out that the production code wouldn't allow most of the material Rogers found objectionable to be seen in films anyway. Sure enough, the adapted screenplay was "clean" enough for Rogers.
Ginger Rogers wore a dress in the film which instantly became so popular that to this day, the style is known within the garment trade as a Kitty Foyle dress. Characteristically, this would be a sleeved dress in black or navy with a white or ecru collar and cuffs.
After Ginger Rogers' Oscar win for this film, she returned to RKO and was greeted by staffers and actors in top hats and tails.
This was RKO's biggest hit of 1940, earning $869,000 in profits.
