Re: If you had to bring in the REAL Mandarin how would you do it?
Had to? I'd love to!
I'd say Killian is shown to have some sort of mental control over his Extremis soldiers and (after being exploded by Pepper) takes over Trevor Slattery's body. So it's Ben Kingsley's Mandarin with Killian's mind.
Haha. We were talking about this a lot when IM3 first came out. It's been a while though. :P
