I don't have any complex plans for playing a character. I think all I try to do is not make too many bad guy faces and not ever try to seem too good. I just try to put it in the middle somewhere.
Before I had a son, I used to look at my father's example: he left me, he left my mother. When I had a son, I got caught in the same situation that his mother don't want me to see him. I started looking at my father in a different light.
