If you haven't watched a good Manga film in a long time I highly recommend Sword of the Stranger.

one of the best I've seen in a while. It's about Chinese imperial warriors hunting for a little boy in Japan whose blood can supposedly create a potion of immortality.

It's got the works, Nameless Samurai hero's, snarky kids, ninja dogs and plenty of amputation by sword action. I watched it with my boys last night and we loved it.

I will check this out.
