- Irony as She Is Cast: Ann Miller was a professional dancer. Her character, Essie, is a terrible dancer. This happens quite a bit with Essie, such as when Annaleigh Ashford played her on Broadway. Ashford did such a good job dancing horribly that she got nominated for a Fred Astaire Award.
- Playing Gertrude: Lionel Barrymore (Martin Vanderhoff) plays Jean Arthur's grandfather in the film. In reality, he was only 22 years her senior.
- Written-In Infirmity: Shortly before filming began, Lionel Barrymore lost the use of his legs to crippling arthritis and a hip injury. To accommodate him, the script was altered so that his character had a broken leg, and Barrymore did the film on crutches.
