Acting is half shame, half glory. Shame at exhibiting yourself, glory when you can forget yourself.

Olivier's was, to my mind, the definitive Macbeth. Olivier had murder in his heart the moment he came on the stage.

Just let the wardrobe do the acting

On the stage he was natural, simple, affecting, 'Twas only when he was off, he was acting

Without acting I cannot breathe.

What is acting but lying and what is good lying but convincing lying?
