I think being an actor in general is acknowledging that we are constantly playing different roles, that we have all these different parts of ourselves and instead of pretending that you are just one thing, as an actor you get to admit that you've got all this stuff going on.
Most of us aren't crazy psychotics, but most of us are a whole bunch of different people. I think when you are in a position of authority, that doesn't remove that from you.
I always think extremism is basically a reaction out of fear. What we seem to be experiencing is polar extremism that keeps people from coming together.
