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 Fred joined in the dance after Ginger was finished singing.
Irving Berlin's "The Night Is Filled With Music" was not filmed but instead played as background music in the release print.
A comic scene in which psychiatrist Tony Flagg (Fred Astaire) attempts to analyze a light-headed patient (Grace Hayle) was deleted from the release print.
In her 1991 autobiography, "Ginger: My Story," Miss Rogers related that the entire film originally was planned for Technicolor. However, other sources, including Arlene Croce's "The Fred Astaire & Ginger Rogers Book," a lauded study published in 1972, maintained that just one Irving Berlin song, "I Used to Be Color Blind," would have bust into Technicolor during the dance. Miss Croce explained that color tests were shot, but their quality was poor, so the scheme was dropped.
Of the ten Astaire-Rogers match-ups, this picture contains the least musical sequences - just four.
