A variation of Aldrich Killian appears in the 2013 Marvel Cinematic Universe film Iron Man 3, portrayed by Guy Pearce. The co-developer of the Extremis virus, and the founder of the think tank A.I.M., this version’s characterization is an amalgamation of Simon Krieger and Mallen.[5][6] Initially a sickly individual, he was snubbed by Tony Stark in the past and swore revenge. Over the years, through A.I.M. and with the aid of co-conspirator Maya Hansen’s designs, Killian had A.I.M. further research and develop the Extremis formula, which imparts varying levels of strength and resiliency to human subjects. Some test subjects resulted in death via various explosion, but Killian recruited Eric Savin and Ellen Brandt to his cause. At some point, he also funded the Ten Rings organization by masquerading as the Mandarin (without the true leader’s knowledge) and used British actor Trevor Slattery to maintain this illusion while Killian’s Extremis experiments are seen as terrorist attacks. After kidnapping President Matthew Ellis with the intention of an execution on live television, Killian and his Extremis-soldiers are defeated and killed by Iron Man, James Rhodes, and Pepper Potts.
