EXCLUSIVE: Mike White is back in business with HBO. I’m told the payweb has picked up the pilot script Mamma Dallas, which White wrote and will direct. The plan is to shoot first quarter of next year, and no cast is yet attached. HBO would not comment. White’s previous HBO series was the critically beloved Laura Dern starrer Enlightened. UTA-repped White is scribbling on numerous films, and perhaps the highest-profile effort is his adaptation of Silver Linings Playbook author Matthew Quick’s Love May Fall, which Sam Raimi is in talks to direct at Sony.
