Fear the Walking Dead casts Jenna Elfman as new series regular

Fear the Walking Dead is beefing up its thinning ranks.

After a season 3 finale that left the fates of many characters up in the air, the Walking Dead spinoff has added Jenna Elfman as a series regular, AMC announced Wednesday.

The Dharma & Greg alum will be joined by fellow newcomer Garret Dillahunt (Deadwood), who is also coming aboard as a series regular. Details about their roles are currently being kept under wraps.

Fear the Walking Dead is going through a bit of a transition heading into season 4. In addition to co-creator Dave Erickson exiting as showrunner, season 3 featured the deaths of Travis (Cliff Curtis) and Ofelia (Mercedes Mason), both of whom had been with the show since the beginning.

Elfman, best known for her Emmy-nominated run on Dharma & Greg, most recently starred in the one-season ABC comedy Imaginary Mary. For Dillahunt, his casting comes as he wraps a three-season run on The Mindy Project.
