Thanks to its Jerome Kern/Ira Gershwin/Yip Harburg score and the luminescence of stars Rita Hayworth and Gene Kelly, Cover Girl has taken on a legendary status in recent years. In truth, the film has a banal and predictable premise: a chorus girl (Hayworth) is given a chance for stardom by a wealthy magazine editor (Otto Kruger), who years earlier had been in love with the girl's mother. Offered an opportunity to be a highly-paid cover girl, our heroine would faithfully remain with her tacky nightclub act if only the club manager (Kelly), whom she pines for, would ask her. He loves her too, but doesn't want to stand in her way, so he fakes an argument to send her packing. You don't need a crystal ball to known that the girl and her guy will be reunited for the finale. Phil Silvers, everybody's best friend, and Eve Arden, Kruger's acid-tongued assistant, provide comic relief. The story sags badly at times, but the fans went home happy thanks to the powerhouse musical numbers, including Long Ago and Far Away and Kelly's famous "alter-ego" dance. The film skyrocketed both Hayworth and Kelly to superstardom, and didn't do Silvers any harm, either. Cover Girl is an extraordinarily lavish Technicolor production from the usually parsimonious Columbia Pictures.
