You can't make theater happen without actors. The actor is the central ingredient in making theater happen. Audiences may come to theaters to see the work of stage managers, directors and producers, but the only people who can communicate theater magic to audiences, through ideas and emotions, are the actors. They are the only ones who can communicate this by themselves, and if necessary, they can get along without you. But you can't make theater without the actor.
Laurence SterneI was acquainted once with a gallant soldier who assured me that his only measure of courage was this: upon the first fire, in an engagement, he immediately looked upon himself as a dead man. He then bravely fought out the remainder of the day, perfectly regardless of all manner of danger, as becomes a dead man to be. So that all the life or limbs he carried back again to his tent he reckoned as clear gains, or, as he himself expressed it, so much out of the fire.
