Tony Stark (Robert Downey Jr.) reiterates his famous last line from 2008's Iron Man in the new TV spot for Iron Man 3. Unlike his proclamation in the Marvel Phase I movie which started it all, Tony Stark has a new sense of purpose when he says, "I am Iron Man" as he battles The Mandarin (Ben Kingsley) while trying to keep Pepper Potts (Gwyneth Paltrow) safe from danger. Check out these action-packed scenes, which also feature Guy Pearce as Aldrich Killian and Don Cheadle in his Iron Patriot suit.
