Heading into its fourth season, Fear the Walking Dead has cast Dharma & Greg actress Jenna Elfman in a series regular role. Details on Elfman's character have yet to be announced.

Season 3 of Fear the Walking Dead ended in dramatic fashion with the death of Troy (Daniel Sharman) at the hands of Madison (Kim Dickens), and a decision made by Nick (Frank Dillane) to blow the dam, which left the fate of many characters up in the air. All we know is that at least Madison is still alive. Even if all the main characters make it out in one piece, the group still has plenty of problems to sort through on the next stage of their journey. Troy's death has left Nick and Madison more divided than ever, Salazar (Ruben Blades) has even more reasons to want to kill Strand (Colman Domingo), and new villain Proctor John (Ray McKinnon) may come looking for them.

Jenna Elfman has been added to the main cast for season 4 of Fear the Walking Dead in an undisclosed role. Elfman posted the news of her casting on Instagram, saying she is "so honored to be a part of this." The actress, known mostly for her role as Dharma in Dharma & Greg, is generally associated with comedy, making fans wonder if her role on Fear the Walking Dead is intended to lighten the show's typically dark tone.

Just yesterday, Fear the Walking Dead cast Garret Dillahunt (The Gifted) as a series regular. Like Elfman, details of his character's role remain under wraps.

Dillahunt and Elfman will help fill the holes left by many series regulars who were killed off in season 3. With a cast of 12 series regulars, only five remain on the show. At the beginning of the season, the characters were dealt a crushing blow with the shocking death of Cliff Curtis' Travis, the male lead of the series. In episodes that followed, Luciana (Danay Garcia) decided to leave the ranch, Jeremiah Otto (Dayton Callie) was killed by Nick, Ofelia (Mercedes Mason) died from a zombie bite and Jake (Sam Underwood) was killed by Troy's zombie hoard. In the season finale, fans lost both Lola (Lisandra Tena) and Troy. Depending on the consequences of the dam's destruction, the death tally could get even higher.
