Jenna Elfman has joined the cast of “Fear the Walking Dead.”

According to The Hollywood Reporter, Elfman will appear as a series regular in the upcoming Season 4 of the AMC series. While details about Elfman’s role are being kept under wraps, it seems that her character will be involved in the crossover between “Fear the Walking Dead” and “The Walking Dead,” as the actress shared an image teasing the much anticipated TV event on Instagram shortly after her casting was announced.

Elfman is best known for her role as Dharma on the ABC sitcom “Dharma & Greg,” for which she won a Golden Globe in 1999. Her other TV credits include ABC’s “Imaginary Mary,” CBS’ “Accidentally on Purpose,” and NBC’s “Growing Up Fisher” and “1600 Penn.”

News of Elfman’s casting comes just one day after it was announced that “The Gifted” actor Garret Dillahunt was also cast as a series regular in the upcoming season.

Elfman and Dillahunt join the series after executive producer Dave Erickson stepped down from his role as showrunner following the Season 3 finale. Andrew Chambliss and Ian Goldberg now run the show with “The Walking Dead” boss Scott M. Gimple on board as executive producer.

More casting news for the new season are expected to be announced as the series looks to repopulate its world after Season 3 saw the deaths of series regulars Travis Manawa (Cliff Curtis), Ofelia Salazar (Mercedes Mason) Jeremiah Otto (Dayton Callie), Jake Otto (Sam Underwood), Troy Otto (Daniel Sharman) and Lola Guerrero (Lisandra Tena).

While the fate of nearly every character on the show — except for Kim Dickens’ Madison — is up in the air following the destruction of the dam at the end of the Season 3 finale, Erickson told The Hollywood Reporter last October that he’s confident that the new showrunners will continue to tell the story of Madison, Nick (Frank Dillane) and Alicia’s (Alycia Debnam-Carey). “[If I were to stay on the series] there was definitely more story I had for Nick and Madison and Alicia. I would want to keep that core Clark family going for a while long,” Erickson said. “[But] I’m sure the [new] guys will.”

“Fear the Walking Dead” Season 4 premieres in 2018 on AMC.​
