The Paris Review interview with Matt Weiner is a cornucopia of great writing advice, from adapting sit-com situations to drama to scenes in which everyone has a secret. You can read it here: Paris Review - The Art of Screenwriting No. 4, Matthew Weiner The "Interview" tab leads to a huge selection of interviews with other great writers. Most relevant to us: Bradbury, Gibson, Delaney and Le Guin. I would also recommend the interview with John McPhee, as well as all his books, because he's America's greatest living writer.
