Another high-level showrunner departure for an AMC series. AMC just announced that it has renewed flagship drama The Walking Dead for a fourth season. But Glen Mazzara, who had served as showrunner following the abrupt departure of creator/original showrunner Frank Darabont early into the second season, is leaving. Speculations about Mazzara’s future on the show started when AMC didn’t follow its regular routine of giving The Walking Dead an early pickup despite the record-breaking ratings performance of the show’s recent third season. There had been rumors that Mazzara was not happy on the show and may follow the slew of other showrunners who have departed AMC series – The Walking Dead‘s Frank Darabont, whom Mazzara succeeded, Rubicon creator/exec producer Jason Horwitch exited during production on its first and only season, and most recently Hell On Wheels showrunner John Shiban, who left after two seasons.
Good news about the renewal but what is it with AMC and their showrunners?
