The end of The Avengers was a great fight. We got to see the team fight like never before. For the characters that have appeared in other films, this showed what they had been working up to. With the success of their victory, having the team members go off and continue to live their lives without any repercussions would almost feel as if something was being taken away. What the filmmakers did was show the human side to these heroes. And that's something more we'll be seeing in Iron Man 3.
In an interview last week with MTV, Kevin Feige discussed some of what Tony Stark will be dealing with.
So much of the journey of 'Iron Man 3' is informed by Tony's experiences in 'The Avengers. It's almost like post-traumatic stress: he really has retreated after the events of 'The Avengers' into his workshop, where he's building advanced versions of his suits. He has [designed] a version of the suit that can latch onto him in individual pieces ... anytime, anywhere. As he starts to realize, it's basically because he doesn't want to be out of the suit: he's seen a lot of things in 'Avengers' and has encountered a lot of powerful people, much more powerful than he is.
It brings us back to the Tony we met in the first part of 'Iron Man' where he's removed from that convoy and brought to the cave with nothing but a box of scraps. It's fun for all of us to watch Tony try to figure out how to get out of that scenario. Much of the movie is Tony in the middle of the country without his tools and a fairly broken suit to help him. But that's his superpower: he wasn't born on Asgard, he wasn't hit by gamma rays, and he doesn't have the super soldier serum. His power is his brain. It's fun to put Tony Stark in a corner with nothing and see how he can get out of it.
It was also mentioned that Tony Stark will have to rediscover how to become a hero. From what we've seen of the trailer, this is something he's going to need to do really quickly when the Mandarin attacks. He won't have too much time to sit around his workshop as his home gets destroyed. Whether or not this is the event that jump starts Iron Man as a hero once again remains to be seen.
Iron Man 3 will be released on May 3, 2013
