This was the first RKO film that Fred Astaire and Ginger Rogers did in which they are the central characters. In the first two they play wise cracking supporting roles, and if you don't know what is going on you might say "Hey, why don't Gene Raymond and Delores Del Rio get out of the way and let Fred and Ginger do their stuff?". It was because Fred and Ginger as a team were a bit of a surprise to RKO.
At any rate, like I said, this seems like a warm up for "Top Hat" a year later, but it is still a great film. But the two share a few pieces of the basic formula. Fred and Ginger meet in such a way that annoys Ginger and gets Fred interested, and once Ginger begins to return Fred's affection a complete misunderstanding that Fred knows nothing about causes Ginger to lose all interest in a now confused Fred. Edward Everett Horton plays Fred's loyal but befuddled friend, and Eric Blore, who at first seems like a minor character who is in the film mainly to flummox Horton's character plays a much bigger part in the plot than you would ever imagine. Erik Rhodes plays an Italian who never really has a chance as third vertex in a triangle in which the other two are Fred and Ginger, but he plays that part with great comic style.
A couple of mistakes fixed by "Top Hat" that this one has - First, Fred Astaire is given no solo dance numbers. Second, too much Alice Brady can get annoying. In "Top Hat" her part is taken by Helen Broderick who had a great dry comic wit.
Still, highly recommended.
