From Bleeding Cool:
Yeah, I don’t think this has been reported anywhere, but I actually left my position at Under The Dome a few months ago. It was the great thrill of my life to help adapt one of the best book’s ever from my all-time hero, but I’ve got two very young kids at home who I never got to see last season, so I’m enormously grateful to CBS and Amblin for letting me out of my contract a little early. I’m already missing the cast and crew, but the show remains in the excellent hands of our veteran showrunner Neal Baer, and we were lucky enough to hire some heavy hitting new writers for this season, including none other than Mr. King himself. His first episode is easily the best of the series so far, and helps set the tone for a fucking crazy new direction, so I look forward to getting to watch as a fan with everyone else.
