Is Ginger the better actor?
This movie causes me to wonder: was Rogers a better actor than Astaire?
He's regularly charming, but at least until the 1950s (and maybe even then) Astaire was always in the same emotional state. Rogers, even in this light musical, registers more depth in her characters.
He might have been the most amazing dancer, and in this movie we learn that he can play the piano, too, and he has a nice (though not overwhelming) voice - but it is she who can be morose, angry and silly.
