From this wonderful post by Lance Mannion:
But his admiration for them had grown way beyond simple identification.
He admired them for what they could do.
At some point it had dawned on him that movie acting required more than looking and sounding good on film. It took talent and skill and his favorites had more of that than most other movie actors. He started asking himself why that was so, and how that was so. How did they do that? What exactly were they doing to achieve the effects they achieved?
