Who is the main villain in 'Iron Man 3'? That is the question, isn't it? For a while, we thought Mandarin, played by Ben Kingsley, would be the main bad guy. Then a report came out saying this Marvel character wouldn't be featured as much in the film as expected, leading us to believe Guy Pearce's Aldrich Killian would be the primary threat. But even that is no speculation as Pearce himself stated that his role is no more than a cameo.
So who will be giving Tony Stark the most trouble? Recently discovered evidence suggest it might be someone (or some people) we already know.
