"…and it’s something that happens with Raging Bull, also. And Marty Scorsese’s notion of sound — the memory. Sound memory is so important in Raging Bull; when you see the scene where Robert De Niro shows Cathy Moriarty his father’s house and tells him about the bird — “It was a bird, it’s dead” — and what’s going on around in the street, and you realize how important sound is. The other thing is the acting: Joe Pesci and Robert are so great together. I mean, the hardest thing in the world to do is just shoot two people in a room. All these other things are very easy to do — you get 150 people, you turn your camera on, you create a situation and as long as nobody looks at the camera you can make them seem very real. [Two people in a room] is really difficult. If I think of Robert Duvall, say, talking to Al Pacino in The Godfather two, when Al says to him, “Well what’d you get my son for Christmas?” and he says, “I got him a little car,” and Robert Duvall puts his hand over the couch — these are gestures that people understand as human gestures and they bring you into the storytelling."
