Writer J.D. Salinger is one of America's most influential authors. His novel 'The Catcher in the Rye' has sold more than 60 million copies. But no Salinger book came out after the early 1960s, as the author increasingly withdrew from public life. A new documentary film, Salinger, by director Shane Salerno, examines what Salinger was working on during the last half of life. Film contributor Milos Stehlik joins us to discuss the film.
