Sam Rockwell's Justin Hammer has become the center of attention in a newly-found image from "Iron Man 2". The fresh picture is put out and front by Coming Soon, and captures the multi-billionaire businessman, who happens to also be Tony Stark's rival, speaking in front of what seems to be a government hearing.

How Hammer plays a part in the movie is yet to be disclosed, but earlier Don Cheadle has talked about the strains the War Machine suit will bring to the relationship between Stark and Rhodes. "We kept asking ourselves: How does that play out with Tony Stark being an independent contractor doing what he wants to do, and Rhodes actually being in the military," he told MTV. "There's a real chain of command he has to follow."

"Iron Man 2" stars once again Robert Downey Jr. and Gwyneth Paltrow who reprise their roles as Tony Stark/Iron Man and Pepper Potts. They are joined by Don Cheadle who will take on Colonel James 'Rhodey' Rhodes in place of Terrence Howard. Mickey Rourke, Scarlett Johansson and Samuel L. Jackson join them in the star-studded cast ensemble.

The script of this superhero film is written by "Tropic Thunder" co-scribbler Justin Theroux. So far, the plot of this sequel is yet to be disclosed, though rumor has it, Stark will be dealing with his alcohol problem. Directed once again by Jon Favreau, it is set to hit U.S. theaters on May 7, 2010.
