Millennium Actress.
Have you seen it? I did watch it for a short course in filmmaking and I wrote a paper on it. If you ask me what it's about, I don't really know. I could say agree it's a story about Setsuko? and how she became an actress and also her career as one.
There's some love story in there too but everything is mixed up between reality and film. I think it was more for art than any real narrative. It is beautiful.
