This could quite possibly be the coolest version of Iron Man yet. This anime "will be produced by super studio Madhouse, responsible for classics like Ninja Scroll, Vampire Hunter D: Bloodlust, Trigun, Millennium Actress, [and] The Girl Who Leapt Through Time, Hajime no Ippo." Video after the break.
There is also a clip at Technabob for Wolverine from the same studio. Doesn’t look as promising though. I think they Japanese stylized him a little too much.
