This was the first Fred Astaire-Ginger Rogers film to lose money on its initial release. It lost $68,000 (~ $1.48M in 2024) for RKO according to studio records.
Fred Astaire refused to sing the Irving Berlin song "The Yam" because he thought it was silly, so Ginger Rogers sang it alone. Astaire would eventually record the song, which can be heard in his collected works.
Fred Astaire's golfing sequences were filmed April 14 and 15, the month before principal photography began, at an improvised range at the RKO Ranch. He performed just to a piano--the orchestral score was added in post-production.
In her 1991 autobiography, "Ginger: My Story," Ginger 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 burst into Technicolor during the dance. Croce explained that color tests were shot, but their quality was poor, so the scheme was dropped.
Of the 10 Fred Astaire-Ginger Rogers pairings, this movie contains the fewest musical sequences--just four.
