The debut trailer for Iron Man 3 is officially here, highlighting the coming sequel's conflict between Robert Downey Jr.'s titular superhero and Mandarin, brought to life by none other than Sir Ben Kingsley. You also get a few peeks at Downey Jr.'s Tony Stark struggling with his post-Avengers New York City catastrophe demons (in a bottle, perhaps?).
There are a few specific things you should be watching for. A quick shot of Mandarin's ten ring-bearing fingers, the Ten Rings of Power that the super-villain found in a starship (in the comics). You'll also get a peek at the Iron Patriot (US flag-themed armor), worn in the comics by the villainous Norman Osborn during the Marvel Universe's catastrophic Civil War. Osborn won't be a player in Iron Man 3, so I'm guessing the Iron Patriot duties will fall to Aldrich Killian (Guy Pearce, also seen in the trailer), in a nod to the comics' Extremis arc.
