I did know that, but I haven't seen it. Maybe that can be next week's movie.
This story really has a lot of undertones and a few different versions. I didn't realize that when I started translating from the Japanese script I used as a reference. The more I looked into it, though, the more I found. In my text, I tried to keep it simple and plain without delving into the history of Kagura and other details that are often included in the story.
