Joan Didion’s “The Year of Magical Thinking” is coming to Broadway. “The memoir, which was published in October and has since sold more than 200,000 copies, is to be adapted for the stage by Ms. Didion herself, with an eye toward a spring 2007 opening on Broadway. The play, imagined as a one-woman show, will be produced by Scott Rudin, the Hollywood and Broadway producer, and directed by David Hare, the respected British playwright. No casting has been announced.”
