I realized the exciting place was behind the camera with the producer, director and so on.

To me the only real star of the movie is the writer. And I work with writers very closely, from outline to first draft and on to the seventh draft, whatever it takes.

You have to kill the bad guy.

After the war, there was no industry. We lost the war. We had our whole city destroyed. No money. No studio. No film. No camera. No equipment. We would shoot in the street. We had no actors. Nothing. But we wanted to do movies. And we did the best movies in the world.

Nobody taught Picasso how to paint - he learned for himself. And nobody can teach you to be a producer. You can learn the mechanics, but you can't learn what's right about a script or a director or an actor. That comes from instinct and intuition. It comes from inside you.

The pope dies, you get another pope.

If you get a book which is 600 pages, you have to reduce it to a script of 100 pages. In two hours of film, you cannot possibly include all the characters.
