Betty Grable was 39 when she made this film, her last to be released, and her constant references to herself as a girl seem peculiar. Even more disturbing is the way she imitates the singing style of Marilyn Monroe in her numbers. She had just made "How To Marry a Millionaire" with Monroe and had commented that she felt she was handing her crown on to Monroe. But to see the great star Grable trying to be Monroe is a little sad.
The film itself is a mess of a thing - some good dance numbers featuring Marge and Gower Champion (Marge's fantasy sequence is very fine) and some good songs ("I've Got a Crush On You", "Someone to Watch Over Me")sit uncomfortably with the plot and the director never seems sure which style he is aiming for. It looks like an attempt to cover the breezy free style of the Gene Kelly/Stanley Donen musicals, with characters bursting into song all over the place and elaborate dance dream sequences. But the result is a confusion of styles and a plodding pace.
The plot concerns married Grable discovering her presumed dead first husband is still alive. She must then choose between new husband Gower Champion and old husband Jack Lemmon (who also happen to be a show writing team). This potentially serious situation, that probably occurred a lot after the war, is treated completely flippantly - and with Gower's real life wife hanging around it's not hard to guess how things will turn out. Lemmon is good, but looks uncomfortable singing and dancing. See this for the numbers - but make sure you see it in Cinemascope.
