When you watched him today, did you also remind yourself that you were watching another example of the action/need to make your listener(s) see what you see in your mind's eye and that it comes from your body? Did you notice that each sentence conveyed an idea and that emotion was produced from that idea? As well, here was another example of what happens when the clarity of the images/ideas profoundly affects its listener(s) -- the quality of their silence -- the stillness of their collective attention.
I think that the actor's task is to reach for this kind of concentrated reality, regardless of the genre of the drama.
