Maggie Grace is getting "Lost" in "Fear the Walking Dead."

The actress is joining the cast of AMC's hit spinoff of "The Walking Dead" as a series regular for Season 4. Details of her character have not been revealed yet.

She joins Jenna Elfman and Garret Dillahunt, who are also jumping on board the show, which is undergoing something of a reset. New showrunners Andrew Chambliss and Ian Goldberg are taking over, some notable characters were killed off last season (including leading man Cliff Curtis' Travis), and the finale cliffhanger indicated the setting would change to Houston, Texas.

Earlier this week, "Talking Dead" revealed that Lennie James' Morgan is the crossover character that had been teased by producers. He finished filming the current eighth season of "Walking Dead" recently and immediately joined the "FTWD" production in Austin, Texas.

"Fear the Walking Dead" premieres sometime in 2018 on AMC.
