David O. Selznick
He doesn't hit, he doesn't pitch, he doesn't field, he's not even directing the action like the manager. But when everything's working, you sense the hand of the Big O's perfectionism. The embodiment of all the good qualities of the word "producer" – visionary, passionate, unerring in his taste. Famous especially for Gone with the Wind, but I celebrate him for A Star Is Born, Rebecca, and The Third Man – and for his obsessive, exhausting, endless, and utterly fascinating mountain of memoranda, collected in Memo from David O. Selznick.
