'The Walking Dead' Spinoff In 'Incubation'

The Walking Dead spinoff is in development at AMC, but programming head Joel Stillerman said there is no clear plot for the follow-up series yet.

In a joint interview with network chief Charlie Collier for Vulture, Stillerman said that The Walking Dead spinoff is not as far along as the Breaking Bad spinoff Better Call Saul, and that series creator Robert Kirkman is still writing the comic on which the series is based and finishing up the fourth season of the zombie drama.

"[The spinoff] is really in the incubation stages," Stillerman said. He also said that Kirkman had a specific vision for The Walking Dead that he laid out in the first issue of the comic.

"And I encourage anybody who's interested in the show to go read the note that he wrote in the first issue of the comic," he said. "His motivation for telling that story was so clear and so powerful, and it served as such a great north star for the show."

Stillerman also said Kirkman is trying to figure out an idea to give him a clear vision for the spinoff.

"What is going on [now] is a more philosophical discussion over why there should be another version of the show," he said. "Once we answer that, we'll zero in on the specific creative."

Although Stillerman said there isn't a definite plot for The Walking Dead spinoff just yet, executive producer Greg Nicotero did offer some insight as to what fans could expect, or not expect.

"We're sort of treating the spin-off as a completely separate entity. That was something that was very, very important when the notion of a companion series was even brought up," he said.

"The actors and the executive producers wanted to make sure that anything we did, we didn't want it to diminish our story, our storyline, our characters and the momentum that we have. So the intent is that it is going to be its own standalone world."

Robert Kirkman has also hinted that the spinoff will detail how the zombie apocalypse came about. He also said that the spinoff will not be set in Georgia, where The Walking Dead takes place, in order to further remove it from its predecessor.

The Walking Dead returns on February 9.
