Funny you mention its theatricality. This came across like a very theatrical film, and the huge sets made me think I was sitting in the balcony of a theater watching a play. Tonight I watched Charleston and The Little Matchgirl which certainly were interesting. I believe I had seen Charleston as part of some avant-garde program but that one was highly amusing. Renoir seemed to be making films in a very classicalist sense. Nana comes across as a stale Porter adaptation, and these two films, particularly Charleston seems straight out of Mellies. Interesting films in their own right and I can't help but admire anything remotely surreal.
