I have The Seven Samurai on the other computer: since I am very ill now, I'll watch it (I still haven't finished watching Troy. Watched half of it then went to sleep and forgot about the movie completely).
As for The Last Samurai being a product and Hollywood, I tell you: "A rose by any other name would smell as sweet".
The quote above can be reversed but I don't want to offend you so I won't put Zatoichi and biological by-products in the same sentence. Peace!
