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.
Betty Grable's dancing partner in the number "Once Too Often" is choreographer Hermes Pan, who did the choreography of this film.
"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.
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. The famous picture of Betty in a swimsuit taken from the back with her looking back over her shoulder was done this way because her pregnancy was well advanced and it showed. The feeling was that a pregnant Grable was not as much of a pinup.
