"I said, 'I'm a big boy. I can handle any snub. I can handle anything,' " Affleck, 41, said on "Late Night with Jimmy Fallon" this week about the warning he received before signing on. The criticism was not unexpected.
But the actor told Fallon accepting the role did take some serious thinking. "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?' "
Once he was locked in for the role, the father of three says the studio wanted to get him ready for an onslaught of negative comments.
"The people from the studio were like, 'We're thrilled! And listen, we want to talk to you, because people go through this process and it can be a little trying.' " Though he was instructed to stay off the Internet for a few days to avoid the murky depths of comments, Affleck couldn't help but check out the response.
"I can handle (stuff). I'm very tough," he said.
Affleck, who is married to actress Jennifer Garner, will star in Warner Bros.' currently untitled 2015 Batman-Superman movie alongside Henry Cavill of Man of Steel.
