Star Marion Davies had seen Leslie Howard on Broadway in "Berkeley Square" and insisted that he be her co-star in this film, even though MGM production head Irving Thalberg wanted Clark Gable. When first meeting Howard in person at Hearst's estate San Simeon, she was surprised at his height and made Howard wear lifts in his shoes.
The Marion Davies character of Jennifer Rarick is called "poor little rich girl", a nickname attached to heiress Barbara Hutton, on whom her character is based.
The $5,000 Jenny casually wants for her participation in the charity function equates to over $96,000 in 2022.
When the camera pans up the side of the Rarick Building, it's actually the Empire State Building.
