Syfy has announced the cast for “Z Nation,” a post-apocalyptic zombie series set to premiere this fall.

Harold Perrineau, Tom Everett Scott, DJ Qualls, Michael Welch and Kellita Smith have joined the ensemble drama from “Sharknado” production company The Asylum.

Perrineau will play Hammond, the leader of the group headed west; Scott will portray Garnett, Hammond’s second-in-command; and Qualls takes the role of Citizen Z, a computer hacker who joins the team and helps them navigate the zombie-infested terrain. Welch and Smith are Mack and Addy, respectively, two disparate wanderers drawn to the team — and to each other — by a shared goal: survival. Also in the ensemble are Anastasia Baranova as Addy, Russell Hodgkinson as Doc, and Keith Allan as Murphy.

Per Syfy: In “Z Nation,” three years have passed since the zombie virus has gutted the country, and a team of everyday heroes must transport the only known survivor of the plague from New York to California, where the last functioning viral lab waits for his blood. Although the antibodies he carries are the world’s last, best hope for a vaccine, he hides a dark secret that threatens them all. With humankind’s survival at stake, the ragtag band embarks on a journey of survival across three thousand miles of rusted-out post-apocalyptic America.

Karl Schaefer serves as executive producer and showrunner on “Z Nation.” John Hyams will direct the pilot. The series is produced by The Asylum and sold internationally by Dynamic Television.
