EXCLUSIVE: Robert Downey Jr. Explains Where He Stands On 'Avengers,' 'Thor' And Joss Whedon

Sure, we know "Iron Man 2" star Robert Downey Jr. will blast into theaters next week as Tony Stark, but what about "The Avengers"? And what does he think about "Thor"? And while we're at it, is he a fan of rumored "Avengers" director Joss Whedon?

These are the questions on many fans' minds when it comes to the most prominent face in Marvel's movie future, and they were some of the questions we posed to Downey when he caught up with him this weekend at the "Iron Man 2" junket. And while the actor stopped short of revealing any big spoilers, he did offer some great insight regarding his new role as a spokesman for the Marvel movie universe and the rest of the films that might get a cameo from Tony Stark down the road.

"I don't know," said Downey when asked if his participation in "The Avengers" was a done deal or if there might still be some negotiation down th road. "I try not to think about that stuff, because everything changes in success, and everything changes in lack of success."

Adding that he has yet to see a script for the superhero team-up film, Downey said he also wasn't familiar with the work of rumored contender for the "Avengers" directing gig, Joss Whedon.

"I'm not very familiar with the guy, but I will let Marvel make whatever decisions they deem appropriate," he said.

However, the actor said he has visited the set of "Thor," Kenneth Branagh's upcoming take on Marvel's god of thunder.

"I take it fairly seriously," he said. "As a bit of an ambassador from Marvel, it's important for me to just show up and let these guys know there's a presence and an awareness, and a gratitude, and a bit of a commiseration — because these are tough movies to pull off."

"I think between the casting and Branagh at the helm, I particularly feel that 'Thor' is on a really solid page right now," said the actor, giving a vote of confidence to the project.

As for "Thor" star Chris Hemsworth, Downey had nothing but praise for the actor charged with wielding Mjolnir, the magic hammer of the gods.

"It's interesting, isn't it? That guy is compelling even in small doses, so I bet getting to see him fully inhabit an iconic character should be good," he said.
