Jimmy Stewart is Jimmy Stewart, in this film as much as in any. The hoofers, musicians, dancers and others are very typical and very good.
Because of our impressions and biases, we expect something very different in a Jimmy Stewart film. This one is way beyond 'Philadelphia Story', on a scale that runs from that to, say, 'Rear Window'.
This, however, is a very lightweight musical, to be considered closer to the 'Follies' films and shorts like the one about Catalina Island than such heavyweights as 'Carousel', 'L'il Abner' or 'Showboat'.
It actually reads more like a cartoon script than any coherent, literary film such as 'Golden Caddillac', 'Animal Crackers' or 'Bringing Up Baby'. Speaking of the last, it is a pity that JS and KH did not work together more.
The pace is frenetic ala Marx Brothers, the dance and musical numbers done very well and the emphasis is on having the minimum story necessary to string together the music.
There is a subtle but very special scene, near the end, when Paulette Goddard goes to Jimmy's place to rouse him out and get him to the studio for the climactic radio show. It is not a musical number though there is a great deal of physical comedy in the scene. What makes it special special part is, without rhythm or music, that it is very clear that Paulette Goddard is dancing. The blocking, direction and her own talent shine. This one scene is worth the price of admission.
With a story in the best tradition of American Musical Tradition, more talent per actor than many better known and better thought-of films, this is a very enjoyable diversion. I was constantly impressed with the tight writing and talent. Did I mention that the folks are good?
It ain't 'Grapes of Wrath' but 'Pot 'O Gold' is well worth the watching.
