Robert Downey Jr.'s return in Iron Man 3 is just days away for US audiences — and this time around Tony Stark is battling none other than his archenemy The Mandarin. Sir Ben Kingsley portrays the villain, and in this exclusive clip we learn about the background of the character, Kingsley's take on The Mandarin's worldview, and what it was like for those making the film to work with the actor. There's also plenty of Kingsley's low growl — which thus far sounds like the best supervillain voice this side of Bane. If you live abroad, you can check out Kingsley's performance now; for those of you in the US, Iron Man 3 opens Friday.
