Musicals sort of blend into a blur, especially those built around Fred Astair. All the stories are disposable, and you remember them more or less by who his partner was.
This one is different. I does stick to the mature template of how the dances fit in: half the dances are part of a show within a show. The other half spring from the story in that fantastic manner we accept as a matter of narrative convention.
The dances, though, some of them are pretty darn memorable.
To appreciate this, you need to understand the challenge of filming dance. We have the "old" convention in spots here: the camera is in some sort of theater seat and watches a performance on a stage, sometimes a literal stage. There's nothing cinematic about it: you could see the same thing is a live performance.
The challenge is in what to do that works with the dance and at the same time leverages cinema, presumably to engage us. The production team here did some rather amazing things with space. I don't know who to credit, but there's some genius here.
The idea is by steps bonding the dance to notions of artificial space, the actual containing space. It starts with a simple device: Fred dancing with a hat rack. Its a strange thing, halfway between being a partner and an interaction with the world.
Then on a ship, he and Jane dance on a floor that shifts. The notion of an unstable gravity is a pretty amazing notion because Fred's effects all depend on his relationship to the ground and what's on it. The floor shifts and he accommodates, amid moving pulls, rolling oranges and shifting furniture.
Then the most memorable dance sequence shifts this on its head, mastering gravity: he dances in a room starting on the floor. Then dances on the walls and ceiling. The effect is accomplished by having the room imperceptibly rotate and the camera with it. But its an extraordinary achievement the way he plays with it. It isn't as wild as Gene Kelly playing with and in the rain because it is more precise and intellectual. But it is a real thrill. You need to see it.
Later, in the stage show, there's an acknowledgment of all this, a production number about place, with a map of a place that turns transparent to reveal the place itself.

There's a strange background here, the actual royal wedding of the period. The tone of that was supposed to be so obvious and strong that merely being immersed in it would overcome hesitations to wed. Its so flat today it shocks, especially the actual footage of the rather ridiculous pomp.
(The woman playing Fred's paramour is Winston Churchill's daughter, an odd combination of mannish face, red hair, terrific legs, a studied grace and little charm. The man playing the beau of Fred's sister was one of Hollywood's most promiscuous empty souls he married a Kennedy.)
