“Arthur Miller’s first and, I think, only novel, Focus, was, in my opinion, every bit as good as his first produced play, All My Sons. I once asked him why, if he was equally talented in both forms, he chose to write plays. Why would he give up the total control of the creative process that a novel provides to write instead for communal control, where a play would first go into the hands of a director and then pass into the hands of a cast set designer, producer, and so forth? His answer was touching. He said that he loved seeing what his work evoked in others. The result could contain revelations, feelings, and ideas that he never knew existed when he wrote the play. It’s what we all hope for.”
