AMC released a statement Thursday commenting on the news:
"'The Walking Dead''s Glen Mazzara, writer and executive producer, is expanding his responsibilities to assume the role of showrunner. AMC is grateful to executive producer, writer and pilot director Frank Darabont whose contributions to the success of 'The Walking Dead' are innumerable.
We continue to discuss his ongoing role with the series. Robert Kirkman, creator of 'The Walking Dead' graphic novels, executive producer and writer on the series, will remain in this role and will continue to steward the brand. Gale Anne Hurd will remain in her role as Executive Producer. The production continues on schedule for an October 16th premiere."
Comments from the network head are coming shortly.
Last fall's hit zombie show saw behind-the-scenes turmoil after the conclusion of its first six-episode season, but with Mazzara's appointment as the new boss, the drama seems to be cooling off. Production on season 2 is currently underway.
