I do think that good actors can do any part. It doesn't mean that they are the best ones to do it.
When you work as an actor, you've got to feel safe even in what appears to be the simplest things.
Certainly there have been better actors than me who have had no careers. Why? I don't know.
I do my work as an actor, but another part of my work goes to the piece as a whole. I can be fairly detached looking at my work and be brutal on myself.
One of the joys of being an actor is that you're always learning new things. And I've been doing this since I was 19, so there's been a lot of new things I have learned for each part. I always assume that I can do it.
