For a second consecutive time, The Walking Dead is reaching within to replace a showrunner. The series’ supervising producer Scott M. Gimple is finalizing a deal to become executive producer and new showrunner of the hit zombie drama series. Gimple is expected to convene his writing team to begin work on Season 4 in the next two weeks. He replaces Glen Mazzara, who exited when Walking Dead was renewed for a fourth season last month. Mazzara in turn succeeded The Walking Dead creator/director/original showrunner Frank Darabont several episodes into production on Season 2. Both Darabont and Mazzara were removed from the series. Mazzara’s departure is said to have been done under pressure from Walking Dead executive producer Robert Kirkman, on whose comic the TV show is based.
