Cover Girl's importance lies not in its originality as a book (it's a standard backstage Cinderella story), as much as it does in what happened to each of its stars. Gene Kelly was "loaned out" to do it when MGM boss L.B. Mayer didn't have much use for him at his own studio. His performance in this film, coupled with the ground-breaking 'Alter Ego' dance solo (duo?) was so successful that it made MGM take him seriously at last (he was never loaned out again) and allowed him to flourish with the soon-to-come hits of "Anchors Aweigh," "On The Town," and "An American In Paris." Likewise for Rita Hayworth; Columbia had been grooming her for years, but she had done mostly B-level films. CG showed her off as a lead in glorious Technicolor, and paved the way for GILDA, her signature (and much more adult) role. Here she and Kelly make a sweet couple, and dance well in "Put Me To The Test" and the fresh, energetic "Make Way For Tomorrow." They are at their most poignant in "Long Ago And Far Away," but the number (played on piano by Phil Silvers and sung as they both stack up nightclub chairs) seems to beg for a dance number, then doesn't have one. Another good number is the title tune, which pays tribute to the famous American magazines/cover girl models of the day. Hayworth appears as the last model, running down a curved runway in a gold dress with her flaming mane flying behind her. A dream in Technicolor!!
