When we heard Shane Black (the Last Boyscout, Lethel Weapon, Kiss, Kiss, Bang, Bang) was writing Iron Man 3 we got all giddy. But with every week the news gets better… Marvel really seem to have cracked the comic book movie concoction.

With Guy Pearce and Ben Kingsley both onboard in the last few weeks, it couldn’t get better. But then the announcement of Jessica Chastain (The Help, Tree of Life) coming onboard today and the fact that we are now fairly sure the story will be based on the Extremis storyline from the comics, it actually did get better. We know Guy Pearce will play a character called Dr. Aldrich Killian who features, briefly, in Extremis.

Extremis sees Tony Stark being approached by an old romantic interest – who also happens to be a brilliant scientist with a rival corporation – for help as it appears she is heavily involved in a ‘super-soldier project’ that has gone very, very awry. Our money is on Chastain playing the scientist , Maya.

As a side note, the fantastic art of Extremis was by Adi Granov who was brought on as a producer for the first Iron Man movie and he was responsible for the design of the suit in the movie, so it certainly seems as if we’re getting a version of this story.
