Once the voice has done its job, how does the body go on from there? How can we make our characters as real as we can? Every actor asks these questions of themself, but there's one question that Yakim asks about every character--Who are they? Boiled down? In two words, even? This book defines the different types of characters as basic archetypes, or "selves": The Vulnerable Self, The Trusting Self, The Instinctive Self. It then goes on to list ways of developing these Selves from a purely physical standpoint.
I have only used parts of this book in developing some of my characters, and already, I feel more confident about my presence on stage. I believe myself now, and that's the hardest audience to convince.
