I've always been lucky in casting. The trick in casting is to hire great people, and let them do what they do, don't interfere with them too much. And then when they're great, take credit for it in the end.
Woody AllenWhat 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.
