Killian works alongside Maya Hansen (Rebecca Hall) in harnessing the power of nanotechnology, which Tony Stark/Iron Man (Robert Downey Jr.) tries to use to defeat the nefarious Mandarin (Ben Kingsley). The fact he’s got a character poster suggests he’ll be a major park of the movie.
Here’s what the Official Marvel Database has to say about Killian: ‘Dr. Aldrich Killian (Guy Pearce) is a brilliant scientist working for the FuturePharm Corporation in Austin, Texas alongside Dr. Maya Hansen (Rebecca Hall). Together they developed Extremis, an attempt to create a new super soldier. The Extremis is a techno organic virus that completely rewrites the body’s genetic code. It replaces entire organs making them more efficient. The virus also gives the body a sort of healing factor. The original Extremis grants super human strength, speed, endurance, reflexes and the ability to project electricity and breathe fire.’
However in the comics he turns out to be a rather slippery character.
