In an interview with UK paper The Sunday Times (via Dark Horizons) Affleck revealed that his Batman (who he will be playing in Batman v Superman: Dawn of Justice) is one angry Batman, which he can sort of relate to.
The actor said he has a lot of pent-up anger, just like Batman himself, so his on screen portrayal in Batman V Superman: Dawn of Justice will have a ‘character flaw’ of rage.
He told the Sunday Times: “I think it’s a necessity, historically, in the tradition of these films.”
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 with, put up with, put up with…then when it emerges, it’s not something I have a ton of control over.”
“I’m not gonna do a Wolverine berserk rage, but I do have a, I do…”
So just beware of the Affleck. You never know how he may react.
Batman v Superman: Dawn of Justice will be released in April 2016.
