Marvel posted to the Iron Man 3 Facebook page earlier this morning a new Iron Man 3 character poster. This latest poster features Guy Pearce as the brilliant geneticist Dr. Aldrich Killian. Dr. Killian along with Dr. Maya Hansen who is played by Rebecca Hall, develop the Extremis techno-organic virus. This is the third character poster, joining the falling and damage Robert Downey, Jr. as Tony Stark, along with the Don Cheadle as Iron Patriot that was released just last week. Iron Man 3 arrives in theaters on May 3rd, 2013.
