Aru eiga-kantoku no shogai (Kenji Mizoguchi: The Life of a Film Director)
Again there's no Spout link for this movie. I saw it on the DVD for Ugetsu monogatari. The documentary was made by another famous Japanese director, Kaneto Shindô.
Although I think Ugetsu is perfect, it's the only Mizoguchi film I've seen. And the strange Japanese polite yet intrusive interview style was interesting but also tedious after a while. Probably if I had seen more of his films as a reference for what they were referring to most of the time, I would have rated it better. Maybe it's not too fair, but I gave it a rather average rating.
Rating: 7/10
