“We want to reinforce a lot of the stuff we started to tip off,” Favreau told MTV News. “‘The Avengers’ is a much larger concern for Marvel and Kevin Feige, who runs Marvel. They’re going to be doing ‘Thor’ and ‘Captain America,’ and the way we might start to tease those things in this movie, some of it is stuff that we’ve discussed [and] some of the stuff you do last-minute as you figure out how that stuff is coming together.”

“It’s an evolving, amorphous thing,” he explained. “If we decide and commit too early, the secret always gets out.”

“They’ll have to [find a different director], because I’m not going to be available,” he explained. “It’s something I’m being the executive producer on, so I’ll definitely have input and a say.”

“It’s going to be hard, because I was so involved in creating the world of Iron Man and Iron Man is very much a tech-based hero, and then with ‘Avengers’ you’re going to be introducing some supernatural aspects because of Thor,” he continued. “How you mix the two of those works very well in the comic books, but it’s going to take a lot of thoughtfulness to make that all work and not blow the reality that we’ve created.”

“That’s why it’s good that you have the guys from Marvel like Kevin Feige, who knows the books well and has been involved with the making of all the movies, and he’ll be very involved with ‘Thor’ and ‘Cap,’” said Favreau. “You need somebody who has the perspective of all the different franchises to bring them together. I have the myopic vision of just knowing and loving Iron Man.”

This opens up the question, who should direct the Avengers movie?

In the second video, there’s a lot of repeated footage, really milking their Robert Downey Jr. interview. Still worth a watch as there’s a bit more about the action scenes:
