This was a wonderful surprise. Alan Arkin of "The Russians Are Coming" and "Catch 22" details his improvisational acting career. He wanted to be an actor from the age of five, and this book tells his metamorphosis from mimic of the human being to actually becoming a human being and how that metamorphosis changed his life and his acting performances, and later, his workshops. Very interesting read.
May I just say that without these four people right now, I would be perpetually ruined. Without their inspired work I would lose all faith in humanity, because they are real. I am honored to know I share a planet with them.
