Kill!

Kill , Kiru? is a 1968 film directed by Kihachi Okamoto, written by Akira Murao, Kihachi Okamoto, and Shgor Yamamoto and starring Tatsuya Nakadai.

The film is a comically exaggerated exploration of what it is to be a samurai. The characters in the movie either give up samurai status or fight to attain it, and samurai are seen behaving both honorably and very badly. The film has a parodic tone, with numerous references to earlier samurai films.
