Ben Affleck acknowledged that he relates to Bruce Wayne when it comes to how the crime-fighter handles his anger in Batman v Superman: Dawn of Justice.
According to Affleck both he and Bruce Wayne approach to dealing with frustration is a “character flaw,”, but he also feels that bringing that quality to Batman is “a necessity, historically, in the tradition of these films.” Affleck also had the following to say about his anger.
“For me, anger is so deeply buried and contained that when it does kind of come out, it comes out in stronger bursts. I tend to be respectful, polite, get along, put up with, put up with, put up with… then, when it finally emerges, it’s not something I have a ton of control over. I’m not gonna go into a Wolverine berserker rage, but I do have a, I do… I should sit down and say, ‘Listen, I just want to let you know what happened there wasn’t OK’, instead of going, let it go, let it go, let it go … ‘Ah, that’s not a big deal’, until finally you just pop!”
