Disney has started the official marketing campaign for Iron Man 3, built around the reveal of the first trailer - which hits in a few hours. In the meantime they've released a bunch of pictures, including a shot of Sir Ben Kingsley as The Mandarin, and a new teaser poster.
As you can see from the image above, this version of The Mandarin is light on Yellow Peril. I'm interested in finding out the origin of this iteration of the character. The teaser poster is nice, illustrating just how many armors Tony Stark has (would you say he has a plethora of armors?).

There are a couple of other pics floating around out there, but most aren't too interesting. I did like this picture of the Iron Patriot (or whatever they're calling him):

Pictures are from USA Today, Entertainment Weekly and Facebook.
