You would. It's not Akira though.
I totally would.
What? I don't take Akira that seriously. I loved the anime, but not so much that I mind it being completely reimagined.
You throw a bunch of Japanese actors in there and there is no way anyone in the US would watch that film except the diehards, and then they'd still bitch about it. Only way to pull off a "true" adaptation is to get a director with a name that draws, like a Cameron or a Fincher or a Bay, and I don't think that's happening.
So relax a little. There's the manga, and the anime (which still stands up to today's standards). I doubt a live action would top the anime anyway, no matter how true to the story it is.
