I have to admit, a little bit of humor can go a long way to diffuse a situation, and he handles the situation with grace and humor here.
Warner Bros. apparently advised Affleck to stay away from the net for a few days after the casting announcement in order that he might avoid the disparaging fan comments he would receive. Says he, “Well, I’m tough, I can handle it.” After reading one comment he temporarily reverted to the stone age of the pre-internet era. Fun stuff.
