"The Walking Dead" returns with the second half of season 4 in a few weeks, however fans wonder about the "The Walking Dead" spinoff. The spinoff was authored by Robert Kirkman, but it looks like that it would take time to come out. AMC execs Joel Stillerman and Charlie Collier updated on the spinoff project in an interview with Vulture.

"Robert has some things on his plate," said Joel.

Joel mentioned that both "Better Call Saul" and spinoff of "The Walking Dead" are in early stages.

"He continues to write every issue of the comic and hasn't finished season four of The Walking Dead, which he is very intimately involved with and will continue to be. That's really in the incubation stages. The one thing that I'll share is just an anecdote that Robert shared with us. He has such a specific vision that he laid out really clearly in the first issue of the comic book. 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. His motivation for telling that story was so clear and so powerful, and it served as such a great north star for the show. We kicked around a few ideas, but primarily what he's working on is, what is the idea that gives [him] as clear a mandate to make another version of this show as [he] had for the first one? What is going on [now] is a more philosophical discussion over why there should be another version of the show. Once we answer that, we'll zero in on the specific creative."

"What we want to do is not diminish the mothership. What we want to do is find something that everyone involved feels as passionately about as being a unique vehicle and unique enterprise as compared to the original series. We'll take our time, and we'll do it right," mentioned Charlie.

"The Walking Dead" returns with episode 9 after the epic mid-season finale that saw the death of The Governor.
