The movie has already been released in Japan and is getting pretty good reviews (currently 67% on Rotten Tomatoes and 7.7 on IMDB), but if you're living in the US this is our first look at Takashi Miike's film adaptation of the Blade of the Immortal manga. The official synopsis:
Samurai Manji has taken a lot of lives, both innocent and guilty, and now lives life in feudal Japan as a criminal. After being cursed with immortality until he kills enough evil men, Manji meets a young girl who enlists him to be her body-guard. Swearing loyalty, protection and vengeance against the group of sword fighters who slaughtered her family, the unlikely duo set on a remarkable quest to make right against those who did them wrong.
Blah blah blah. It's about samurais and Takashi Miike's directing it. That's all you really need to know. If I had to guess, I'd say the majority of their budget went to fake blood.
