Avengers: Age Of Ultron Cast Will Be At Comic-Con, Says Mark Ruffalo

Mark Ruffalo has revealed that the cast of Avengers: Age of Ultron will be in attendance at this year's San Diego Comic-Con.

"Yeah, we're gonna go out there," Ruffalo told Collider. "We're all flying, we're flying from London.  We're working.  We're shooting.  We're gonna stop and get on a plane and go to Comic Con together.  It's gonna be amazing. There might be some cool new Hulk, Hulk-o, Hulk-o-phobia, Hulk-o-phernalia.  Hulk-a-phernalia!"

Ruffalo also talked about how he had to break his promise to never sign onto a film without seeing a script in order to get in on The Avengers. He's now signed on for nine films, but feels safe in Joss Whedon's hands.

"Well, now I'm signed on, but, you know, I know Joss, we've been talking about it already for a year," says Ruffalo. "I know where he's going, I know who Banner is, so there's a nice continuity there.  I'm a little nervous when someone else comes on and Joss isn't doing the writing and so I've made it to two movies now with him and so I have four more to go.  I feel like who Banner is is established enough now that it's gonna be okay."

Ruffalo also discussed the possibility of a Hulk solo film, and what makes the idea such a challenge.

"He's a tough nut to crack of all of them, I think.  He's the one person who doesn't want to do the very thing that all of us are dying to see him do and he's the one person who doesn't want to be there, [laughs] and so it can get very maudlin, it could get very boring to watch the guy who's moping around who doesn't want to do the very thing that we're all dying to see him do.  And so I think that's the tough part of cracking that nut. I think that's what's made it problematical in the past."

Avengers: Age of Ultron comes to theaters May 1, 2015.
