The Warren Ellis "Extremis" storyline has long been revealed to be the foundation of "Iron Man 3," and with casting ramping up, Pearce has landed the role of geneticist Aldrich Killian in the film. So who is he? We had no idea either, but we hit Google and thanks to this Marvel Universe page we learned that he works at Futurepharm with Maya Hansen (in a role that we presume will be cast shortly) where they develop the Extremis virus that essentially forces the human brain to rewire it's healing center and become stronger as a result. The plan was to take it to the military, but they wind up stealing Extremis from Futurepharm and putting it in the hands of terrorists.
It's a bit of darker role in the Marvel universe, and as such, seems pretty well suited for Pearce, and certainly, his addition raises the talent stakes. "Iron Man 3" starts shooting next month and will hit theaters on May 3, 2013. [Variety]
