Gene Kelly appears here as one of two sailors, with Frank Sinatra playing second fiddle and losing out to Gene in wooing Kathryn Grayson. Gene is usually part of a trio when he plays a serviceman (On the Town, It's Always Fair Weather). The Gerry the Mouse sequence is the usual MGM gimmick for providing Gene with something different, as with roller skates and dustbin lids in 'It's always Fair Weather'and a newspaper in 'Summer Stock'. Columbia had done the same with Gene's 'alter ego' dance in 'Cover Girl'. The main problem with dancers is that without gimmicks they become boring and repetitive. Curiously I don't find this the case when watching Fred Astaire. The black and white format at RKO has a style of its own. But with colour you need gimmicks, as seen with Astaire dancing with his split images in Paramount's 'Blue Skies'. Without Kathryn Grayson this film would be a disaster. The relationship between Gene and Frank is characterless when comparing it with Fred and Bing in 'Blue Skies'. But Gene is good with children, whether it's Dean Stockwell or the kids in 'American in Paris'. For all its minor blemishes one has to remember that this film is a vehicle for Grayson, Kelly and Frank, the last-mentioned being introduced as a sop for the bobby-soxers. If you are looking for a plot, forget it.
