What people who don’t write don’t understand is that they think you make up the line consciously — but you don’t. It proceeds from your unconscious. So it’s the same surprise to you when it emerges as it is to the audience when the comic says it. I don’t think of the joke and then say it. I say it and then realize what I’ve said. And I laugh at it, because I’m hearing it for the first time myself.
I never see a frame of anything I’ve done after I’ve done it. I don’t even remember what’s in the films. And if I’m on the treadmill and I’m surfing the channels and suddenly Manhattan or some other picture comes on, I go right past it. If I saw Manhattan again, I would only see the worst. I would say: “Oh, God, this is so embarrassing. I could have done this. I should have done that.” So I spare myself.
Why does Woody still make movies? Because he can. Because they still let him.
