An actor needs an audience. If an actor doesn’t have an audience, then the camera must replace that void. The audience, or the camera, provides a formality, a structure, that gives the actor permission to leave the area of “comfortable and casual.” It’s the formality of that environment that the nerves of self consciousness are awakened. It is those nerves of self consciousness that stimulate and inspire expression.
If you, the actor try to ignore, deny, repress or worse yet… lose those nerves of self consciousness, you will not be able to access the aliveness, the immediacy, that is the essence of an inspired performance. And, if you deny, repress or lose those nerves of self consciousness you will never understand what Oscar Wilde meant when he said, “I love acting, it’s so much more real than life.”
