In this May 2, 2016 photo, writer-director Rob Reiner poses for a portrait in New York. Reiner has always had an affinity for the father-son story and has explored the theme and his own life in films like "Stand By Me" and "A Few Good Men," but none have come so close as "Being Charlie," loosely based on his son Nick Reiner's struggles with drugs.
