Iron Man 2

In Russia, the media covers Tony Stark's disclosure of his identity as Iron Man. Ivan Vanko, whose father, Anton Vanko, a former Stark Industries employee, has just died, sees this and begins building a miniature arc reactor similar to Stark's.

Six months later, Stark is a superstar and uses his Iron Man suit for peaceful means, resisting government pressure to sell his designs. To continue the legacy of his father Howard, he reinstitutes the Stark Expo in New York City's Flushing Meadows-Corona Park.
