I like that idea a lot. Unfortunately, when Kurosawa and company started writing the script they meant it to be a satire, but as they progressed they decided to change it to a tragedy! That was a bad idea and it shows. Not only is this Kurosawa's biggest box office bomb, but I thought it was way too slow. The other problem is I didn't like anybody in the film. Mifune just acted like a maniac completely out of touch with reality and his family came across as a bunch of greedy pigs. The entire thing was a bummer and time hasn't helped it at all. The movie would have been much better if Mifune's character was pulled back in a little to make his fears seem more realistic and less paranoid. But that's just my opinion, what do I know?
One interesting thing was Kurosawa had the entire cast run 20 days of full rehearsals before they started filming! That's crazy. Also Kurosawa used a three camera technique a lot during this movie.
Skip it.
