'New York Times' writer Dave Itzkoff examines Williams' comic brilliance and struggle with addiction in the biography 'Robin.' Williams took his own life in 2014; an autopsy later revealed he had Lewy body dementia. Also, 'Jessica Jones' star Krysten Ritter says she loves the complex role of the atypical superhero. "I am doing the most work when I'm not saying lines," she says. Netflix just renewed the series for a third season.
