Ben Affleck On Batman Blowback: 'I'm A Big Boy'

Affleck tells Jimmy Fallon that he can handle the flack from his casting opposite Henry Cavill's Superman.

Guess what, trolls? Ben Affleck isn't worried about your Bat Hate. The actor spoke for the first time Monday night about the blowback from his casting as Batman in the upcoming "Superman vs. Batman."

"They called me up and said, 'Do you wanna do this?' And I thought, 'Well, I'm not 25, man. Are you sure about this?'" Affleck told Jimmy Fallon on Monday night about the offer to follow Christian Bale's iconic take on the brooding superhero in the "Dark Knight" series. Once Affleck saw what director Zack Snyder had in mind, he said he was totally sold on the concept.

"It's this incredible take on it," he said cryptically, alluding to the fact that he couldn't imagine trying to mimic what Bale did. "He wants to do something different, but still in keeping with that. I thought, 'This is a brilliant way to do this and I really know how to hook into this.' I said, 'I want to do this.' "

What Does Ben Affleck Need To Do To Become Batman?

Affleck said he was excited, the studio was excited, but then executives pulled him aside for a little talk about the sometimes trying process of putting on the cowl. So, they showed him some of the past reactions from fans on the Internet about other, unnamed, superhero roles.

"They send me [reactions for] people who were in these movies who did a great job and they'd say, 'Kill himmm!'" Affleck said. "You can't say that before a movie comes out. It doesn't matter what you think then, it matters what you think when you see the movie."

Affleck appreciated the gesture, but he told the suits, "I'm a big boy ... I can handle anything." Regardless, they counseled him to stay off the Internet for a few days. "This is not ... I handle s---," he assured them. "I'm very tough."

But, the day the news was announced, Affleck said he looked down at the first comment on the story and it was, "Noooooooo!!!!" So, the computers at Chez Affleck went off for a week.

He wasn't shaken and told Fallon that by the time he makes it to Comic-Con and takes part in the official reveal, things will make way more sense. "When you see the materials ... it's a hard thing to describe without giving away the story and giving away what it is," Affleck said. "I really feel like I have a lot of opportunities now, which is really great."
