Robert Downey Jr. Talks 'Iron Man 3' And 'Avengers,' Says Filming Will Be 'Weird' Without Jon Favreau

We're still a long ways off from seeing "Iron Man 3" in theaters, but when the third installment of Marvel's blockbuster franchise does arrive in theaters, we could be looking at a very different adventure with the iconic armored Avenger, courtesy of new director Shane Black. One thing that won't change, however, is the man underneath the helmet, actor Robert Downey, Jr.

MTV News caught up with Downey on the set of his next film, "Sherlock Holmes: A Game Of Shadows," to get his take on the run-up to "The Avengers," Jon Favreau's departure from the "Iron Man" franchise, and the new guy behind the camera for "Iron Man 3."

"You grow a moustache and then they do something here [points to chin]. That's how easy it is," laughed Downey when asked about his preparation for "The Avengers," Marvel's superhero team-up film that will have him returning as billionaire industrialist Tony Stark. "It's going to be great, once I tell them what to do."

Downey indicated that he keeps in close contact with his former "Iron Man" and "Iron Man 2" director, even though it will be another former collaborator behind the camera for "Iron Man 3."

"[Favreau's] up to great stuff with 'Cowboys & Aliens' coming out," said Downey. "He and I just talked a couple weeks ago and we're quite friendly indeed."

Given the change-up in "Iron Man 3" and the impending climax of Marvel's superhero movie-verse in "The Avengers," Downey said he tries to keep everything in perspective — including his time as Tony Stark.

"It is weird. I think there's always a closure to everything," he said, adding, "This will all come to an end one day, and I think the thing is to just really enjoy it while you have it."
