Stark is sponsoring a Stark Expo at the site of the New York Worlds' Fair, and he flies in for an appearance in the Iron Man suit and promises world peace. The arena is thronged with adoring fans. Imagine Steve Jobs announcing iPad 3. But trouble is brewing. His arch-rival Justin Hammer (Sam Rockwell) plans an army of rival iron suits. A Congressional committee headed by the fatuous Senator Stern (Garry Shandling) wants Stark to make Iron Man the exclusive property of the Defense Department. And in Russia, the bitter Ivan Vanko (Mickey Rourke) believes Stark's father stole the Iron Man secrets from his own father.
