Downey strikes gold for 'Iron Man 3'

In it, the government passes a superhero registration act, which requires those will special powers to reveal themselves to the U.S. government and help with law enforcement, according to Variety.

The awesomeness that is Robert Downey Jr.

Is this Tony Stark or Robert Downey Jr.?

Iron Man is okay with it, while Captain America sees it as a threat to civil liberties and joins the underground.

If Downey inks the deal, it will be another nice payday for the actor. He's expected to earn about $40 million and a share of the box office for his screen time.

Downey has already done pretty well with the three "Iron Man" movies. They earned $2.4 billion worldwide.
