Former The Walking Dead showrunner Glen Mazzara said today that if you want to know why he suddenly lost his job on the hit show last year, he’s not your guy. “When people involved with the show are looking at the long-term plan, you know, they want something different. And what those differences are, you’d have to ask AMC,” he said Tuesday during a session at NATPE. Mazzara exited Walking Dead in December when AMC renewed the breakout series for a fourth season. “I was a hired gun coming in to support the creator of the show and, through odd circumstances, I ended up becoming the showrunner. I was just glad that I was able to contribute and not mess up the show, I see that as a win,” he added to laughs from the crowd. Earlier this month, Walking Dead supervising producer Scott Gimple was announced as Mazzara’s replacement. Mazzara was appearing on a panel in Miami with Lost co-creator/showrunner Damon Lindelof on the second day of the conference. The second part of The Walking Dead’s third season starts February 10.
