The small-screen spinoff from the hit film franchise is set to premiere Sept. 3.

Syfy's and USA Network's upcoming The Purge TV series has tapped a Walking Dead alum to join its cast.

Sabrina Gennarino, who played Tamiel in AMC's zombie series, will star in the scripted drama for both NBCUniversal-owned cable networks, set to premiere Sept. 4.

Announced in April as part of Blumhouse's ITV-backed studio deal, The Purge is a small-screen spinoff from Blumhouse’s hugely successful horror franchise from creator James DeMonaco. Blumhouse TV will serve as the lead studio on the small-screen adaptation, with the 10-episode, straight-to-series drama being written and executive produced by DeMonaco. Emmy-winning The People v. O. J. Simpson director Anthony Hemingway will helm the first episode.

The Hollywood Reporter understands that Gennarino will play a figure called Madelyn, adding to a cast that includes Gabriel Chavarria, Lili Simmons, Lee Tergesen, Jessica Garza and Amanda Warren.

Like Blumhouse's original hit film franchise, The Purge TV series is set in an America under a totalitarian political party rule. Each of the characters must come to terms with their past and figure out how to survive a 12-hour period when all crime, including murder, is legal.

The original team from the films is behind the television series, including executive producers Michael Bay, Brad Fuller and Andrew Form along with Sebastien K. Lemercier from Platinum Dunes. Thomas Kelly is the series’ showrunner/executive producer.
