Obviously, ["Fences"] is a character-driven piece in every sense of the word, and Denzel [Washington] knows the actor. He gave us two weeks of rehearsal. He is a truth teller, and he is a truth seer. So he knows when something is not going in the right direction, and he will call you on it. But, he knows the word to use to unlock whatever is blocking you. So I think he's fabulous and he's a teacher.
