"Act One is a revealing book about the theatre." "It is, of course, a success story, for Moss Hart today is one of the most brilliant, successful and famous figures in the American theatre, both as a playwright and as a director." How did it happen? Not easily. His boyhood and adolescent years were spent in two entirely different backgrounds, and the stories of both are fascinating. With the opening of his first Broadway play, Once in a Lifetime, his world changed abruptly. This book concludes with a detailed telling of the complicated steps whereby that play came into being.
