"I would really hate for someone else to think they could step into my shoes. I wonder who's playing Tony Stark next. Is it you? Is that what you're here to tell me?

"It's funny. Sometimes you have to call for a good old-fashioned British invasion. 'Iron Man 3' is really shaping up to be something special. We start in a couple weeks. I'm sure I'll be leaking secrets to you as we move ahead."

Marvel head honcho Kevin Feige recently likened the character of Tony Stark/Iron Man to James Bond, and revealed that when Robert Downey Jr. decides to hang up the helmet, a new actor would step into the role. Last night at the Tribeca Film Festival MTV caught up with RDJ, who responded (half jokingly) to this, and also commented on how the production is going on..A few great actors are said to be joining the cast of the threequel, though none have actually been officially confirmed by Marvel/Disney yet. When asked about the likes of Sir Ben Kingsley, Guy Pearce and Jessica Chastain potentially coming aboard, Downey said that he could not wait to work with..Actually the rumor is that filming has begun in Wilmington, North Carolina. Downey Jr. was spotted in the area, and word is that the cameras are already rolling. Unconfirmed for now of course, but we will update with any new info.
