Robert Downey Jr. is Iron Man. (Paramount Pictures)
In Iron Man 2, billionaire industrialist Tony Stark (Robert Downey Jr.) risks billion-dollar pieces of equipment to impress guests at a birthday party -- a big mistake for a defense contractor. After all, Stark's reckless debauchery provides the perfect pretext for the U.S. government to take away his Iron Man suit. Explosions, tattoos, and Scarlett Johansson notwithstanding, the disputes between Tony Stark and his antagonists revolve around ownership of the rights to the Iron Man technology. Iron Man 2 is the most expensive movie ever made about an intellectual property dispute.
