“I write entirely to find out what I'm thinking, what I'm looking at, what I see and what it means." As famous in her work as she was enigmatic in her personal life, Joan Didion remains one of the most iconic writers in modern history. Directed by Didion's nephew Griffin Dunne, a documentary of the poet, essayist and screenwriter's life - Joan Didion: The Center Will Not Hold - will launch on Netflix on October 27.
