Samurai Cinema

Hi, I am currently a student from England undergoing a piece of coursework exploring change in style and conventions in 'Samurai Cinema'. I am focusing specifically on the construction of action sequences.

So if anyone has seen any of the following films and like to discuss what you think is evolutionary, or successful, or anything that has changed over time, then your input would be much appreciated.

The Seven Samurai (Akira Kurosawa, 1954)
Yojimbo (Akira Kurosawa, 1961)
The Samurai Trilogy (Hiroshi Inagaki, 1954-56)
Chushingura (Hiroshi Inagaki, 1962)
Harakiri (Masaki Kobayashi, 1962)
Incident at Blood Pass (Hiroshi Inagaki, 1970)
Samurai Rebellion (Masaki Kobayashi, 1967)
Samurai Banners (Hiroshi Inagaki, 1969)
When the Last Sword is Drawn (Yojiro Takita, 2003)
Twilight Samurai (Yoji Yamada, 2002)
Zatoichi (Takashi Kitano, 2003)

If you have any comments, even on other films not listed here your imput will be greatly valued.

Cheers.
