Here's the latest character poster for Walt Disney Pictures and Marvel Studios upcoming film Iron Man 3, courtesy of Empire Magazine.
Below, one can see Guy Pearce as Aldrich Killian, the brilliant geneticist behind the nanotech serum that drove a 2005 story arc in the Iron Man comic series, and which has been partially adapted into the plot of the new Shane Black‘s film.
Dr.Killian works alongside Rebecca Hall's character Maya Hansen who's looking good!

He'll probably get a bigger role in the movie than he does in the book.
The action adventure Iron Man 3 opens in 3D and 2D theaters on May 3rd, 2013 and also stars Robert Downey Jr. back as Tony Stark, Gwyneth Paltrow as Pepper Potts, Don Cheadle as James Rhodes/Iron Patriot, James Badge Dale as Maya Hansen, William Sadler as Sal Kennedy, Jon Favreau as Tony Stark's bodyguard, Happy Hogan and Ben Kingsley as the villainous Mandarin.

Marvel's Iron Man 3 pits brash-but-brilliant industrialist Tony Stark/Iron Man against an enemy whose reach knows no bounds. When Stark finds his personal world destroyed at his enemy's hands, he embarks on a harrowing quest to find those responsible. This journey, at every turn, will test his mettle. With his back against the wall, Stark is left to survive by his own devices, relying on his ingenuity and instincts to protect those closest to him. As he fights his way back, Stark discovers the answer to the question that has secretly haunted him: does the man make the suit or does the suit make the man?
