To everyone's surprise, fifty-five years after the publication of To Kill a Mockingbird, Harper Lee has published another novel. Go Set a Watchman was written before Lee's beloved masterpiece, as director Mary McDonagh Murphy explains in this update of her 2011 documentary Hey, Boo: Harper Lee & To Kill a Mockingbird. Murphy's film, Harper Lee: From Mockingbird to Watchman, sifts through the facts and speculation surrounding Lee and both her novels, and includes interviews with Lee's older sister, close friends, and admirers including Oprah Winfrey, Scott Turow, Anna Quindlen, Tom Brokaw, Wally Lamb and more.
