Dr. Evil sent us the following message about an IRON MAN 3 trailer he got a look at. He outlined the circumstances in which he witnessed this material - and it seems highly, highly probable that the information herein is legit, and represents a trailer being considered for Shane Black's forthcoming picture (due in theaters early May 2013).
Nonetheless, take this with a grain of salt, as Dr. Evil is a first time contributor, and many variations of trailers might be mulled between now and the time material arrives on computer, television, and theater screens.
Here's Dr. Evil...
It opens with a voice over of Tony Stark talking about how the events of New York (I’m assuming the Avenger Movie) changed him, and how he’s just not “into it” anymore. First scene is Iron Man with battle damage, laying down amid rubble and taking of his faceplate to show a bleeding Stark. Scenes of him arguing with Pepper Potts in the armory (cool shots of alternative Iron Man suits including the red white and blue one we’ve seen on your site already), press conferences, Tony looking solemn, Tony talking with someone who looks like a psychiatrist, and a short shot of Don Cheadle in military uniform (no War Machine in the preview). Also one scene of who I presume is the Mandarin, forcefully landing and cracking the ground. However, it looked like a silver Iron Man. I was unable to tell in the brief view who it was (maybe due to unfinished CGI).
We then get a voice over from Ben Kingsley, talking about how there there are no heroes and how he will teach everyone, especially Stark, a lesson. This is over scenes of the alternative Suits getting blown up, Stark going into surgery, and a fleet of helicopters launching missiles which blow Stark’s home up and apart (the CGI looked nearly finished) and sending Stark and Pepper into the sea below. Then a close up of Kingsley with no helmet in the Mandarin armor.
It ends with Iron man underwater swimming towards what looks like his “heart reactor thing”. Then the logo, then stark walking in the snow dragging a large bag, then the logo again.
All and all, a somber trailer, dark and humorless, which seemed more in tone with The Dark Knight Rises than with any of the other Iron Man movies or the Avengers.
This is my first time writing you. I you use this, call me Dr. Evil.
