For me, the second one was a lot of fun. But being able to come back and be out of the suit and do a lot of the stunts and work with the stunt team and do all that physical work was a lot of fun for me. Speaking of the suit, it got a remake in "iron man 3." What was your first reaction when you saw it? I wasn't re. What was wrong with the one machine? The iron patriot is something in the story of the movie, the president wanted a rebrand. And it was a focus group that suicided on the name. That was a tongue and cheek way to come back.
