"This Is It" (music by James V. Monaco, lyrics by Mack Gordon), sung by Betty Grable, was deleted from this movie. The song as filmed has been restored on the DVD from Fox Home Entertainment.
Linda Darnell and Don Ameche were originally set to star team this movie in October 1942 but when the movie was announced as a musical, Darnell was replaced with Grable.
Betty Grable was seven months pregnant when this musical was completed.
Betty Grable's dancing partner in the number "Once Too Often" is choreographer Hermes Pan, who did the choreography of this film.
Angela Blue and Virginia Maple assisted Hermes Pan in working-out the choreography routines for this movie according to the 'Hollywood Reporter' of 10 June 1943. Betty Grable was then taught these "dance patterns".
Robert Sklar in his book 'Movie-Made America: A Cultural History of American Movies' states that Betty Grable's pinup picture was of value to GI morale during the Second World War.
According to an October 1942 edition of the 'Hollywood Reporter', Libbie Block, the author of the source story of which this film was based, was going to be doing the adaptation, but she did not actually work on this movie's screenplay according to this movie's credits and studio records.
According to the 'Hollywood Reporter', the "midget comedy weight-lifters" Hercules and Dolly were listed as being as part of this movie's cast but they do not feature in the final film as it is.
As part of the finale Betty Grable leads a WAC (Women's Army Corps) drill team in some intricate maneuvers. It was decided to use a real WAC drill team, rather than actresses, for this sequence since they were already familiar with the routines.
Feature film movie debut of band leader Charlie Spivak.
The 'Hollywood Reporter' once reported that actor James Engler tested for the leading male role opposite Betty Grable.
The 29 June 1943 'Hollywood Reporter' stated that Hermes Pan would be directing dance routines involving the Roller Skating Vanities of which Gloria Nordskog would star. However, Nord has no listed credit on this picture but apparently was an uncredited roller skating headliner. As such, she appeared as one of the skaters but did not "star" in the picture so to speak.
This movie's closing credits feature an advertisement for the World War II USA war effort at the end of the credits roll. It states: "For Victory - U.S. War Bonds and Stamps - Buy yours in this theatre."
