To me, the greatest actress.

She instinctively understood acting. She wasn't polluted by the horrific theater techniques that most theater actors are unable to let go in a movie, hindering their performances. I don't believe that she suffered emotionally for her roles, on the contrary, I think that she understood that acting is about showing. She remained herself, unaffected inside, and actually PERFORMED, sadness, happiness, fear, all in her body and face, in a way like a silent film actress but with subtlety and proper modulation. In short, she was a natural genius.
