This peppy wartime musical stars Bing Crosby as radio crooner Johnny Cabot, the heartthrob of millions. To escape his frenzied fans, Johnny joins the Navy, where is he ordering to aid a WAVE recruiting drive. He is helped (?) in this endeavor by Betty Hutton, amusingly cast in a dual role as twin sisters Susie and Rosemary, one a shy retiring brunette, the other a bold and brassy blonde (Vera Marshe doubles for Hutton is some scenes). Part of Johnny's recruiting strategy is to stage a musical show, as good an excuse as any for a steady stream of bouncy musical numbers. This is the film in which Bing Crosby and Sonny Tufts, both in blackface, introduce the Johnny Mercer-Harold Arlen standard "Ac-Cent-Tchu-Ate the Positive." — Hal Erickson, All Movie Guide
