- Cut Song: Irving Berlin's "The Night Is Filled With Music" was not filmed but instead played as background music in the release print.
- Deleted Scene: A comical scene in which Tony Flagg attempts to analyze a light-headed patient (Grace Hayle) was deleted from the release print.
- Wag the Director: Fred Astaire refused to sing the Irving Berlin song "The Yam" because he thought it was silly, so Ginger Rogers got a rare chance to sing it alone. Later, Astaire joined in the dance after Rogers was finished singing.
- What Could Have Been: This was supposed to be filmed in color — hence, the "I Used to be Color Blind" number. But at the last moment, RKO decided color would be too expensive.
