Murakami, I believe, and Dunst
The video was directed by McG, of Charlie's Angels and Terminator Salvation fame, but it was also a collaboration with Takashi Murakami himself, who shares a manager with McG.
"What made us select Akihabara for the film," says McG, "is that it is a unique expression of Japanese culture that's not derivative of an American domination. Of course you flip it by getting a very Anglo woman to play the part of the magical princess."
I think it's a little inaccurate to suggest that otaku culture has zero relation to American culture, considering how heavily Osamu Tezuka himself was inspired by Tex Avery and Betty Boop, both Americans-- but I think the project sounds really cool. It's being displayed at the Tate Modern museum in London, in an exhibition called Pop Life: Art in a Material World.
I kinda doubt I could pack my bags for London any time soon, but I know we have a few British folks around-- if any of you get a chance to run by, PLEASE let us know how it is! Hopefully the video will come available to the 'net eventually as well.
Manager? You mean "Agent" or the legendary "Tenpresenter?"
I hope it come out as a video I can buy soon, it would cheer anyone up!
