In my opinion David Milch is the Steve Earle of TV writers...a brilliant American storyteller who has lived a tumultuous and sordid life I could never really relate to and thus am not sure I could ever emulate or even understand his writing methods or process.
But that doesn't mean listening to him discuss his life and process and methods any less fascinating.
From a 2006 MIT Communications Forum conversation with David Thorburn (it's all good, but gets really cooking around 30:00)
According to Variety, Milch has a new series in the works at HBO called Luck which centers on horse racing, including "the owners, gamblers, jockeys and diverse gaming industry players." Michael Mann directed the pilot and it stars Dustin Hoffman.
