That bit with the two guys clashing swords looks like pure Nakamura. I am so hyped for this movie.
Thanks as always for translating that info, Wao. Interesting to hear that Nakamura made what is basically an animatic. In this day and age I don't know why more people don't use them in Japan (maybe they do?). Especially with tools like flash, you can easily throw down some sketches and make them move without even bringing paper into the equation.
I hope we get to see the pilot film at some point, as a DVD extra or whatever. I remember Tetsuya Nishio did an awesome 40 second pilot/advert for Seirei no Moribito which I can't find anywhere but youtube.
