I got quite nice results in my one-question studies, but never wrote up any of the work, because I had set myself impossible standards: in order not to pollute the literature, I wanted to report only findings that I had replicated in detail at least once, and the replications were never quite perfect. I realized only gradually that my aspirations demanded more statistical power and therefore much larger samples than I was intuitively inclined to run. This observation also came in handy some time later.

The Godfather was a very unappreciated movie when we were making it. They were very unhappy with it. They didn't like the cast. They didn't like the way I was shooting it. I was always on the verge of getting fired. So it was an extremely nightmarish experience. I had two little kids, and the third one was born during that. We lived in a little apartment, and I was basically frightened that they didn't like it. They had as much as said that, so when it was all over I wasn't at all confident that it was going to be successful, and that I'd ever get another job.

about 95% of the experiments we do are total failures, and that’s because we’re out there on the leading edge of what’s possible, and most of the time it isn’t quite possible.

Whenever you’re making a movie, especially when you’re writing, you always have self-doubts. I did the first location shooting in Tunisia.

My dad had such a big influence on me, he was kind of all that wrapped into one. Even if we had a guest speaker at our school, or read something in class, or heard about it, I would always go back and check with him. “Is this right? Would you agree with this, Dad?” He had a big influence on me, so he was the guy I went to for advice and the guy I listened to, and still do today.

My dad always told me and my two brothers, “Don’t ever get too proud or too old to say that you love me and to say that you love each other.” “Love” is a pretty commonly used word in our family. When I talk to my brothers now on the phone midday, we always end the conversation saying, “I love you. I love you, bro.”
