"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie onDecember 16, 1940 with Ginger Rogers reprising her film role.
Bob Perry is listed as a cast member by a modern source, but he was not seen in the movie.
The original ending of the movie just had Mary Grey leaving the Borden House, walking down Fifth Avenue, but the sneak preview audience complained at what it considered an unhappy ending. So the ending was changed to its current form, which essentially made it more palatable.
