This from MTV's Splash Page:
"Having read the 'Captain America' movie script and the 'Thor' movie scripts and 'Iron Man 2' and everything, and seeing them all develop, nothing is more exciting to me than the 'Avengers' movie," Bendis told MTV News. "It's absolutely going to be something better than— different than—anything we've seen before."
"I think the challenge is absolutely there. It's an immense amount of work, but the payoff will be gigantic."
The 'New Avengers' writer also went on to say that he was confident a movie of this scale will work.
"My advice is, has been, and will be, that much like the comics, you look at movies like the 'Oceans' movies that have all these different flavors, you put the flavors together and you cook 'em," Bendis said. "It absolutely can be done."
"Look at 'The Great Escape' or other movies that have all these big elements to them, and even elements that don't seem that they would fit can rub up against each other in a very excellent way," he explained. "They really can create something you wouldn't even imagine you had before."
