“Nobody knows anything…… Not one person in the entire motion picture field knows for a certainty what's going to work. Every time out it's a guess and, if you're lucky, an educated one.”

“The horror of knowing someone and living with them and even thinking you're lucky and then wham and now you know that every person is really two people and how can you ever know what the other half is up to.”

“It's a total lie to say there's only one person you're going to be with for the rest of your life. If you're lucky - and if you try really hard - there will always be more than one.”

“Each of us assumes everyone else knows what HE is doing. They all assume we know what WE are doing. We don't … Nothing is going on and nobody knows what it is. Nobody is concealing anything except the fact that he does not understand anything anymore and wishes he could go home.”

“We're all in the dark. We try to find out, but can you imagine anything more ludicrous than one person's opinion of another person? One goes along thinking one knows; but one really doesn't know”

“You're on your own. And you know what you know. And YOU are the one who'll decide where to go…”

“That's the whole point of good propaganda. You want to create a slogan that nobody's going to be against, and everybody's going to be for. Nobody knows what it means, because it doesn't mean anything.”

“It was one thing, after all, to know his feelings for Amanda hadn't changed; it was another thing entirely to face the future with the certainty that they never would.”

“Some of the pictures I work on a long time and they look as if I've knocked them out, you know, and there are other pictures that come off right away. The immediacy can be accomplished in a picture that's been worked on for a long time just as well as if it's been done rapidly, you see. But I don't find that any of these things prove anything really.”

“Don't beat yourself up for not knowing the answers. You don't always have to know who you are. You don't have to have the big picture, or know where you're heading. Sometimes, it's enough just to know what you're going to do next.”
