If you can get past the irrelevant title of this film, you will find it's a solid vehicle for Esther Williams, who--remarkably!--plays an aquatic entertainer. As Christine Duncan, she gets involved in a plot to hook up her sister (Ellen Hallit, played by Paula Raymond) with the sister's boss (Douglas Morrissen, played by John Lund), a rich playboy businessman who sees her only as his secretary. Typical for its day, the plot revolves around getting him to notice her legs more than recognize what a great person she is.
Christine's swimming routines include long stretches of swimming underwater and hiding behind scenery, so that audiences cannot see her well. But viewers of this film are treated to underwater shots and close-ups of her languid stroking. So we know up-front that we have entered the world of a Hollywood fantasy and left reality behind--which is where it belongs in this very stylized story.
The sets and the sights are richly colored, the fashions are well-tailored and sharp, the musical numbers are enjoyable and eye-catching. They are also numerous, because (fortunately) the characters spend plenty of time visiting nightclubs and running into singers and dancers (like Lena Horne and Eleanor Powell). Such numbers interrupt the narrative, but are an integral part of the formula. The music is mostly of the big band genre, with some boogie woogie to spice things up.
As for the acting, Ms. Williams is, in my opinion, always competent. The other leads are also up to the task, though the emotional demands of the script are minimal. This is a lighthearted romance where the musical entertainment is a primary draw. I enjoyed it as such.
