"Screen Director's Playhouse" broadcast a 30 minute radio adaptation of the movie on April 24, 1949 with Fred Astaire reprising his film role.
Fred Astaire cut his shins and ankles on the broken glass generated during "One for My Baby."
Fred Astaire's character says he learned to dance at the 'Arthur Murray' dancing school. Astaire had previously been in a dispute with the company over the unauthorized use of his likeness.
Joan Leslie's mouthed words at the fadeout were intended to be indecipherable.
Bernard Pearce was hired as choreographer but was let go a few weeks before filming.
A Fred Astaire solo dance number (on a railroad track) was cut from the film, although a print containing it was shown in New York until at least 1948.
Cut from the film was a home-front-flavored swing number, "Harvey, the Victory Garden Man" (music by Harold Arlen, lyrics by Johnny Mercer), sung by Ella Mae Morse to the backing of Freddie Slack and His Orchestra.
In one scene Joan Manion (played by Joan Leslie) is asked by Fred Atwell - a.k.a. Fred Burton (played by Fred Astaire) if her boss, Mr. Harriman (played by Robert Benchley), has ever proposed marriage to her: She replies that he has attempted to numerous times, but keeps getting side-tracked by discussions of such things as the "sex life of polyps". It turns out that in one of Robert Benchley's earliest films he played a "Doctor Benchley" in the film The Sex Life of the Polyp where he lectures Women's Clubs on this interesting creature that can change its sex.
In the scene where Mr. Harriman (Robert Benchley) gives Joan Manion (Joan Leslie) the photography assignment, there are several framed pictures behind him which appear to be the famous Vargas girls.
The character played by Fred Astaire refers to Ginger Rogers and Rita Hayworth, Astaire's former co-stars.
The song "Hangin' on to You" was written for the film but not used.
