Book excerpt: Alan Arkin knew he was going to be an actor from the age of five: "Every film I saw, every play, every piece of music fed an unquenchable need to turn myself into something other than what I was." An Improvised Life is the Oscar winner's wise and unpretentious recollection of the process--artistic and personal--of becoming an actor, and a revealing look into the creative mind of one of the best practitioners on stage or screen. In a manner that is direct, down-to-earth, accessible, and articulate, Arkin reveals insights not only about himself (and his audience and students), but also truths for the rest of us about work, relationships, and sense of self.
