The director is the captain of the ship, without question. No matter what their talent or energy level is, everyone on the crew has all eyes on the captain. If they come in going, "I don't know.

One time, many, many years ago, I had the opportunity to dye my hair brunette for a film. And the day I walked out of the hotel where I had it done, I walked out onto the street and realized people looked me in the eye and greeted me good morning. I'd never had that experience before! And I began to notice that a brunette is treated as an affable human being. Later, when I dyed my hair for Lois Riley blonde, and then Alice Ward blonde, people come right up to you, they touch you on the arm, they ask you how you're doing. Men and women both! Blondes have more fun.
