To explain why he considers Redford’ performance in All the President’s Men such a great performance, he speaks at length about performing with one’s eyes and compares it to his role in The Darkest Hour. He says:

It’s in the eyes. He’s not traveling away from himself vocally or physically, or doing all the pyrotechnics. There’s something about the psychology. I will always say this to students of acting—we talk about phone acting… There’s an example in Darkest Hour when I’m on the phone with Roosevelt. Often you’re not speaking to the other actor; someone is reading the lines in the room or you’re not even getting any of the feed. There are people who are very good at it and people who are not good at it. In All the President’s Men, there is one take of Redford switching phones, talking to different people; it’s about six or seven minutes long. Very, very slow push in on Redford. And I would say to students, “You want to see phone acting? That is the Michelangelo of phone acting.”
