I don't know how many people can claim to have worked with legends like Akira Kurosawa AND Masaki Kobayashi. The amount of classics he had a hand in is staggering.
Rashomon (1950)
Ikiru (1952)
Seven Samurai (1954)
Throne of Blood (1957)
The Hidden Fortress (1958)
The Bad Sleep Well (1960)
Harakiri (1962)
The Sword of Doom (1966)
Samurai Rebellion (1967)
Dodes'ka-den (1970)
Now I want to check out the two films he made with Toshio Masuda. Also Revenge (1964) looks and sounds like my kind of movie. (After killing a high-ranking officer in an illegal duel, a low-ranking samurai is declared insane and challenged to a fixed duel by the vengeful clan to which his dead opponent belonged to.)
