Joss Whedon explains why Jeremy Renner and Mark Ruffalo are right for THE AVENGERS

Apparently MTV.com caught up To Joss Whedon and asked him why his two newest additions: Jeremy Renner and Mark Ruffalo are perfect for Hawkeye and Hulk, respectively. Here's what Joss had to say.

“The thing about Hawkeye, he’s got his bows and arrows, you need somebody who’s very very down to earth, who’s very grounded, and who’s going to be the kind of guy who, you see him, and you understand why he likes to be far away from things and then shoot at them,” Whedon said, adding that without the right actor in the role things could get “very silly” if handled incorrectly. “[With] Jeremy, he just has a lovely quality.”

With regard to Ruffalo, Whedon says the celebrated actor was his “first and only choice for Bruce Banner.”

“I’m stunned that we landed that, just stunned," he said. "He has what I remember loving about the show, that quality of, you just look at him and you go through it with him, he invites you in in a way that [no] other performer has since Bill Bixby. He is a guy who’s been beaten up by life, but not defined by that. That’s what I want from Bruce Banner, is a guy who’s still getting it done, even though he has his problem.”

What do you think of his choices?
