The production number "The Lady In The Tutti-Frutti Hat" ran into problems with the censors. The Hayes office at first considered the way the gigantic bananas were held in front of the dancers as being too "phallic". The problem was resolved by having the dancers hold the bananas at waist level rather than at hip level.
Director Busby Berkeley was free to do this film because Arthur Freed had him fired from Girl Crazy (1943) after he shot the film's ending number, "I Got Rhythm", due to Judy Garland's collapse due to overwork. Norman Taurog took over the direction of "Girl Crazy" and, rather than pay him his contract salary for not working, MGM loaned Berkeley to 20th Century-Fox for this film.
On loan from MGM, Busby Berkeley, directing and choreographing this Twentieth Century-Fox musical, was given his first opportunity to work using perfected, three-strip Technicolor. Thirteen years before, Mr. Berkeley had choreographed for producer Samuel Goldwyn the Eddie Cantor frolic, Whoopee! (1930), shot in early Technicolor.
