It's very stage-y - we won't actually see the utopia, just the faces of the characters talking about it from a weird castle overlooking the wonderful city. They go into it, and then return to the castle to talk about it. The upper class characters mainly hate it, and the working class ones mainly love it. From their descriptions it seems a very limited sort of utopia - clean houses and streets, gardens, and everyone happy in their jobs.
The frame tale is a man and a woman, both in uniform, talking about what England is going to be like after the war, and a stranger (played by J B Priestley, who wrote the play and the film screenplay) comes to describe the story to them.
I couldn't help noticing the accents - which along with the clothes, were the class markers for the characters. The posh accents felt authentic; after all, there's plenty of actual footage of posh people talking from that period, and they more or less all sound like Queen Elizabeth. The working class accents felt wrong - a lot of substitution of "eh" sounds for "ah" sounds - did working class people actually speak like that in the 1940s, or is that just how posh-speaking actors thought they spoke?
