Now that Tony Stark has gone public with his alter-ego "Iron Man" - there is no telling what evil force will come forward to battle the invincible "Iron Man!"

Reports say that Rourke would play a tattooed Russian heavy named Ivan who becomes a man with deadly, technologically enhanced coils. While another source adds that Rourke would play the Crimson Dynamo. "He's considered to be an evil version of Iron Man because he battles the superhero in a nuclear-powered suit of armor."

Rockwell would play Justin Hammer, a multibillionaire businessman and a rival of industrialist Tony Stark, AKA Iron Man, being played by a returning Robert Downey Jr.
