The new biopic about reclusive author J.D. Salinger explores his formative years, from struggling writer, to serving in World War II, to publishing his famous and controversial 1951 novel, "The Catcher in the Rye," to using meditation to deal with PTSD. Actor Nicholas Hoult, who plays Salinger, and Danny Strong, who wrote and directed the film, are both meditators themselves and talk about diving into this tortured author's mind to bring his story to the big screen.
