Anyone who knows anything of history knows that great social changes are impossible without feminine upheaval. Social progress can be measured exactly by the social position of the fair sex, the ugly ones included.
I think it's an actor's responsibility to change every time. Not only for himself and the people he's working with, but for the audience. If you just go out and deliver the same dish every time ... it's meat loaf again ... you'd get bored. I'd get bored.
