The world of The Walking Dead is about to get a whole lot bigger. The show celebrates its tenth anniversary this year, and there were big announcements at Comic-Con with a new spin-off series announced, a sixth season of Fear the Walking Dead, and the news that Rick Grimes will return … Only in theatres.

The Walking Dead movie will reportedly solve the mystery surrounding Rick’s departure by helicopter last season, while the new series will focus on a group of young adults who’ve led a sheltered life during the zombie apocalypse.

“They know what Walkers are, they know how to kill them, but they’ve never done it,” said TWD content officer Scott M. Gimple.

The bombshell announcement at this year’s Hall H panel came from Danai Guirira, who confirmed this is the last season she will be playing Michonne.

“I’d just like to say that this has been one of the purest joys of my life, to play this role, and to be amongst these people and those that are not here right now and amongst all of you. I’m very, very thankful for the experience I’ve had in ways that I can’t even express right now.”

And with the comic book series coming to an end, creator Robert Kirkman assured fans that the show’s future is secure… for now. “I cannot thank all of you enough for the support,” he said. “If anyone is concerned that the comic book wrapped up means that Season 10 is going to spontaneously end on Episode 4 as a surprise, that’s not going to happen.”

The epic-looking Season 10 trailer also debuted, promising the return of the Whisperers and Michonne brandishing Lucille. “We’re getting into a totally different kind of war,” teased showrunner Angela Kang. “The Whisperers are a totally different kind of enemy, so we’ll get to see a Whisperer war.”

“There’s a whole lot of people losing their sh-t this season,” added Norman Reedus. “There’s a lot of paranoia this year. The threat is right next to us and you can’t tell who’s who.”
