At his classes in the technique of acting, Lee laid down the rules, supervised the first exercises. These were largely concerned with the actor’s arousing his inner temperament. The essential and rather simple technique, which has since then been complicated by teachers of acting who seek to make the Method more recondite for their commercial advantage, consists of recalling the circumstances, physical and personal, surrounding an intensely emotional experience in the actor’s past. It is the same as when we accidentally hear a tune we may have heard at a stormy or an ecstatic moment in our lives, and find, to our surprise, that we are reexperiencing the emotion we felt then, feeling ecstasy again or rage and the impulse to kill. The actor becomes aware that he has emotional resources; that he can awaken, by this self-stimulation, a great number of very intense feelings; and that these emotions are the materials of his art.
