Just one month after AMC's Fear the Walking Dead wrapped up its third season, casting is already under way on Season 4, with Garret Dillahunt (The Mindy Project) signing on as a series regular. No details have been given for his character in Fear the Walking Dead Season 4, but the casting comes almost exactly two years after the actor, a big fan of the Walking Dead franchise, stated on social media that he wanted to play Negan. While his tweet got quite a bit of support on Twitter, the role ultimately went to Jeffrey Dean Morgan, with Garret Dillahunt later thanking the fans and adding that hopefully he'll get "something else some day," hinting that he'd still try to land a role in this universe, and it seems that's finally happened.

This casting comes as the show is undergoing some big changes behind-the-scenes. Dave Erickson, who co-created and developed the series with Robert Kirkman, is parting ways as showrunner, with Once Upon a Time executive producers Andrew Chambliss and Ian Goldberg coming aboard as showrunners, while The Walking Dead showrunner Scott M. Gimple has also come aboard as executive producer. Scott M. Gimple's involvement came a few months after it was finally confirmed that there will be a Fear the Walking Dead crossover with the flagship series The Walking Dead, which may be one of the reasons why Gimple suddenly became an executive producer on Fear the Walking Dead.

The crossover announcement came at New York Comic Con, where Robert Kirkman confirmed that one character from The Walking Dead will cross over to Fear the Walking Dead. While that character has not yet been confirmed, many have already speculated that the crossover character is none other than Abraham Ford (Michael Cudlitz), who was killed by Negan in the Season 7 premiere last year, along with Glenn Rhee (Steven Yeun). While that character was not yet confirmed, Michael Cudlitz himself did put out a rather cryptic tweet around the time of Kirkman's announcement, stating, "Crazy s--t is about to go down. See y'all on the other side."

Abraham being the crossover character makes sense for a few reasons, one being an opportunity to bring a beloved character back to the franchise, and another being the fact that the new season will be set in Texas, the home state of Abraham Ford. This new report claims that AMC will be filming the new season in Texas, following the Fear the Walking Dead Season 3 finale, where the new villain known as Proctor John (Ray McKinnon), states that they will set sail to, "what's left of Houston." It was established in both the comics and the TV series that Abraham Ford is from Houston, where he and his wife Beth and their two children survived along with other members of their community in a local grocery store.

It's possible that Garret Dillahunt is playing one of the new characters we'll meet in Houston this coming season, although whether or not he has any connection to Abraham Ford, or this potential crossover, remains unclear. There has also been talk that this Walking Dead crossover could actually happen in The Walking Dead Season 8, but that has yet to be confirmed, and there were no further details about this crossover in today's report from The Hollywood Reporter. Garret Dillahunt is just coming off The Mindy Project, where he played Jody Kimball-Kinney since the beginning of Season 4, with the series finale airing last night on Hulu, and he also stars as Dr. Roderick Campbell on the new Fox series The Gifted. Take a look at the tweets from Fear the Walking Dead executive producer Gale Anne Hurd, welcoming Garret Dillahunt to the show, along with his response.
