I generally don't have much interest in films from that era, but that sounds amazing. I may have to hunt it down.

Yay! As someone who is interested in films from that era (and will spam you with recommendations if you're not careful you'd like some), I will repeat my caution that much of Berkeley Square does feel like someone just taped the play, but the montage and the movie's ambivalence if not outright pessimism about its central conceit are sufficiently striking that I would recommend it. I'm not sure of its status on DVD. Apparently it was a lost film for about forty years.
