The "Moneyball" actor says while he had no reservations about playing a gangster in new movie "Killing Them Softly", he does have to draw the line somewhere for the sake of his kids with fiance Angelina Jolie, reported Showbizspy.
"Violence is an accepted possibility when you are dealing with crime. I would have a much harder time playing something like a racist or something along those lines.
"It would be much more unsettling for me than a guy who shoots another guy in the face! This is the world we live in so I see it absolutely important to film," he said.
