In an interesting twist of fate, it seems that Marvel is seeking out yet another actor in the midst of a long awaited comeback to go toe-to-toe with Robert Downey Jr. in Jon Favreau's upcoming sequel Iron Man 2. According to Variety, Mickey Rourke is currently in talks to play the villian opposite Downey Jr.'s hero in this new action adventure. And Sam Rockwell is set to play Justin Hammer, a multibillionaire businessman and a rival of industrialist Anthony Stark.

In the upcoming sequel, Rourke will play Iron Man's nemesis Crimson Dynamo. The character has been described as Tony Stark's Russian alter ego. He is a heavily tattooed bruiser involved in the arms trade. And he will battle Iron Man in his own nuclear powered suit. A report from The Hollywood Reporter has different take on the villian, though. They say that Rourke will be playing a Russian heavy named Ivan who becomes Whiplash, a man with deadly, technologically enhanced coils.
