More after the jump!
Marvel President, Kevin Feige, had this to say:
So Iron Man 3 has been structured specifically to be the antidote to The Avengers... Circumstances in the story separate Tony from having access to anything.
We wanted to take Tony back to, metaphorically speaking, the cave from Iron Man, the first half of Iron Man, when he's cut off from the world and needs just focus on his intellects to get himself out of his situation.
So he's not calling Thor, he's not calling Captain America, he can't press a special button to have the helicarrier come rescue him, so I think that'll be a nice complement to the team up of Avengers.
