Fifty years after winning the Pulitzer Prize, To Kill a Mockingbird remains a beloved bestseller and quite possibly the most influential American novel of the 20th Century. The film version, starring Gregory Peck as Atticus Finch, won a trio of Academy Awards, and in April the Postal Service will issue a stamp honoring Peck - depicted wearing glasses, as Finch. Hey, Boo explores the To Kill a Mockingbird phenomenon and unravels some of the mysteries surrounding Harper Lee, including why she never published again. It also brings to light the context and history of the novel's Deep South setting and the social changes it inspired after publication. Anna Quindlen, Tom Brokaw, Wally Lamb, Richard Russo, Oprah Winfrey, Andrew Young and others reflect on the novel's power, influence, and popularity, and the many ways it has shaped their lives.
