Filmmaker and producer Judd Apatow (Superbad, Girls, The 40-Year-Old Virgin) talks about his late mentor, stand-up legend Garry Shandling, and the personal trauma that formed him. "Garry was a wounded person. He was a neurotic man," Apatow says. "He was a guy constantly attempting to evolve and heal. I felt like there's so many lessons that people can get from learning about how he lived his life." Apatow explores Shandling's life and legacy in the HBO documentary 'The Zen Diaries of Garry Shandling' and the accompanying book, 'It's Garry Shandling's Book.'
