SFX Magazine recently got to chat with The Avengers director Joss Whedon, who spoke about the main difficulties in bringing this ensemble movie to the big screen. Here's an excerpt from the site's article:
"What I will struggle with, in the outline and throughout, is that I would like to put these actors in a room and just make Glengarry Glen Ross," he laughs. "We're talking about really exciting people and at the same time I have to keep the momentum of the thing going. I can't let it turn into a lull fest. Knowing that I have enough time to do both of those things - that by the end of the movie you will feel 'in' with these guys - is the trick. It's not an easy one but one that Marvel absolutely honors. They don't hire Mark Ruffalo [the new Hulk] to say one iconic line and strike a pose. They hire him because he has so much humanity in him. He's the antithesis of the iconic actor. He's so human. He was my first choice to play the part, and the fact he is playing the part is nuts! They went to great lengths to make that happen and they understood exactly why he was right for the part."
