I found this by accident on Amazon Prime Video. It's quite a surprise. It's a good movie imo. It's worth checking it out if you are into Samurai Period dramas. It's not an action movie though. The cinematography is great, acting is good, but really hard to judge because the movie is set within a movie/drama setting (if that makes sense). The main actor doesn't speak much because he's been a side actor his whole life (both in the movie and in real life). The main actress is great though. She actually is a skilled chinese sword practitioner. I think it's mislabeled as a "Documentary", but there is some insight in the movie on how Japanese period dramas are made. It also shows the life of "extras".
