Just watched very good documentary about the Japanese Samurai Actor Toshiro Mifune who teaming up with Akira Kurosawa made a number of classic movies The 7 Samurai, Hidden Castle, The Samurai Trilogy. The Yojimbo movies. etc. There are interviews with people he worked with his sons. A real treat is you get to meet one of the trio of actors that sided Mifune, in Kurosawa's movies he was a Samurai, in Toho studio's other movies he was the person in the Godzilla suit. You can watch it on NetFlix.
