Guy Pearce is a baddie of some sort in Iron Man 3; he plays Aldrich Killan, a guy who develops a nanotechnology known as Extremis. That tech will play a huge role in the film, but how big will Pearce's part be? I had heard he had a fairly minor role, but here he is starring in a character poster. Maybe this is a fake out, and he gets Marion Crane-d pretty early. Or maybe Killan is very important to the film.
Either way, he looks like he's starring in a new reboot of Miami Vice. Even his white lab coat looks like it's straight out of Crockett's closet.
