Ultimately, physical resemblance isn't as important as whether this person can bring this character to life in a way that's compelling and makes me care about what happens to them.
There are times when I am directing, and there are a couple of moments I didn't get the way I wanted, but I know I still have other angles to shoot and I have to be done by noon; I move on.
I try to tell the best story, and the story that has some heart and some genuine terror and some social commentary and some comedy and some romance and some sex and some violence.
I definitely see the good in people. Certainly in my own life I strive to be somebody who is functional and well adjusted and can face conflict in a non-emotional and non-destructive way, and those are the people I try to surround myself with in my life. But as characters, they bore me.
I guess in America we're so sold on this ideal of the perfect, well-adjusted family that is able to confront any conflict and, with true love and understanding, work things through. I'm sure they do exist, but I never knew any of them.
