Fear the Walking Dead isn't going anywhere, as the spin-off series has officially been renewed for season 6. This news came as part of the show's panel at San Diego Comic-Con. It's not the most surprising reveal, given AMC's plans to keep the Walking Dead universe going for as long as possible. But for fans of the show, it's surely welcome nonetheless. On top of that, it's also been revealed that a trio of new cast members will be joining in on the action as the zombie apocalypse moves forward.

On hand for the Comic-Con panel were showrunners Andrew Chambliss and Ian Goldberg, executive producers Robert Kirkman, Dave Alpert, Gale Anne Hurd, Greg Nicotero and Michael Satrazemis, as well as Scott Gimple, who oversees the Walking Dead franchise for AMC. Cast members Lennie James, Alycia Debnam-Carey, Danay Garcia, Maggie Grace, Jenna Elfman, Alexa Nisenson, Austin Amelio, Rubén Blades and Karen David were also in attendance. Gimple revealed during the panel that Colby Minifie, Peter Jacobson and Colby Hollman will be joining the cast of Fear the Walking Dead, in addition to revealing that they've been picked up for another season.

To go along with the season 6 announcement, a trailer for the second half of season 5 was also released, in addition to a new clip, which we have for you to check out. The trailer, for something taking place in a post-apocalyptic nightmare, has an oddly optimistic tone. We see that the survivors are documenting their experience, which could, dare we say, introduce a found footage element to season 5 when it returns. Optimistic, relatively speaking, as it may seem, there is plenty of carnage and walker action to go around.

The clip features the opening minutes from the upcoming episode, which is set to air this Sunday ahead of the mid-season break. It focuses on Morgan and the rest of the survivors who are using their radio to see if anyone else is alive. It all seems hopeless, with no response. That is, until the end of the clip brings in a little surprise. It ties into what Scott Gimple revealed at the panel, indicating that this world is much larger than we previously thought.

"The big secret is that there have been other civilizations that have survived the apocalypse. We are about to show a lot more."

So there are more people out there than just the groups we've been following in these two shows. Perhaps this is how the currently untitled, third Walking Dead series will be teed up? Maybe this will be further explored in the trilogy of Rick Grimes movies? Which we learned are going to be released in theaters, by the way. Ratings be damned, the zombie apocalypse is here to stay and it's only getting bigger. Fear the Walking Dead airs Sundays on AMC.
