For those of you not familiar with the character, Justin Hammer is a rival of businessman and inventor Tony Stark. Hammer had, at one time, been denied an opportunity to purchase Stark’s own Stark Industries. Seeking revenge, Hammer used his vast fortune to discredit Tony Stark and his bodyguard, Iron Man, on numerous occasions. Unless extensive make-up will be used for the character, Rockwell’s character will be a much younger version of the Iron Man villain.
Justin Hammer will not be the only villain to cause Iron Man trouble. For several weeks now, other villains such as The Mandarin, Black Widow, and the Crimson Dynamo have been revealed to play a part.
Along with the Rockwell rumor, MTV's Splash Page reported on January 7th that Mickey Rourke was in talks with film executives to play either the Crimson Dynamo or another Iron Man villain called Whiplash. When asked if Rourke had been cast yet, Sam Rockwell told MTV, “I hope so!”
