What exactly is Ben Kingsley's The Mandarin going to be up to in Iron Man 3? According new 90-second featurette from Marvel Studios, he's going to be weaponizing an invention that'll be quite familiar to readers who have kept up with Shellhead's adventures over the past decade or so.

Check out the video, which contains minor spoilers about the plot of the movie, after the jump.



Clearly, extremis, the serum introduced in Warren Ellis and Adi Granov's "Extremis" arc in Iron Man in 2005 and 2006, will play a huge role in what takes place in the film, powering actor James Badge Dale's baddie Savin and other Mandarin henchmen.

It isn't clear how closely the movie will follow the "Extremis" arc--which, notably, The Mandarin didn't appear in, though he did try to release the virus in a later arc--though director Shane Black describes its use in the movie as the next step in human evolution.

Iron Man 3 opens in theaters May 3.
