Following the surprising news that Frank Darabont has stepped down as showrunner, The Walking Dead has released a statement that officially promotes Glen Mazzara to the position:

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 Oct. 16 premiere.
