Gary Oldman & Helena Bonham Carter Offered Roles For Akira?

Twitch is reporting that Warner Bros. have offered another two roles for Akira. This time is it's Gary Oldman for the role of the Colonel and Helena Bonham Carter as Lady Miyako. Neither are strangers to genre based projects and are darlings at the studio. Oldman and Carter previously worked together in the Harry Potter franchise. It's not out of the question that these heavy weight actors will end up in the film but it's simiply a rumor at this point. Morgan Freeman had long been rumored for the role that Oldman is being offered. Garrett Hedlund (Tron Legacy) apparently is the front-runner for one of the leads.
