In the circle of light on the state in the midst of darkness, you have the sensation of being entirely alone... This is called solitude in public... During a performance, before an audience of thousands, you can always enclose yourself in this circle, like a snail in its shell... You can carry it wherever you go.
Constantin StanislavskiWhen you're playing a character who's cruel, look for the places where he's kind. When you're playing a character who is unhappy, look for the places where he has a glint of merriment.
