BREAKING: Iron Man 2 Villains Cast!

Mickey Rourke (The Wrestler) and Sam Rockwell (Frost/Nixon) are in talks to star as the villains in Marvel Studios’ Iron Man 2, being directed by Jon Favreau from a script by Justin Theroux, according to Variety and The Hollywood Reporter.

THR says that Rourke would play a tattooed Russian heavy named Ivan who becomes a man with deadly, technologically enhanced coils. Variety 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,” says the trade.

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.

Rourke and Rockwell would be joining a cast that also includes the returning Gwyneth Paltrow and Don Cheadle, who is replacing Terrence Howard.

Another part — one for Stark’s assistant Natasha — is still open.

The project is eyeing a spring start in Manhattan Beach. Paramount will release the movie May 7, 2010.
