Rey Gallegos is in the Zone… the demilitarized zone.

The Mexican actor will star in HBO Max’s DMZ, a limited series based on the DC comic series from Ava DuVernay, Roberto Patino and Warner Bros. Television.

Gallegos joins a cast that includes Rutina Wesley, Mamie Gummer, Nora Dunn and Henry G. Sanders.

Also joining stars Rosario Dawson and Benjamin Bratt are Venus Ariel, Jade Wu, Agam Darshi and Juani Feliz.

Joining the creative team are filmmaker Ernest Dickerson and Emmy winner Carly Wray.

Dickerson will direct and executive produce three episodes of the four-part series. DuVernay directed the first episode and executive produces the series.

DMZ is set in the near future, when America is embroiled in a bitter civil war, leaving Manhattan a demilitarized zone (DMZ), destroyed and isolated from the rest of the world. It chronicles the harrowing journey of fearless and fierce medic Alma Ortega (Dawson) to find the son she lost in the evacuation of New York City at the onset of the conflict. Throwing gasoline on the flames of that conflict is Parco Delgado (Bratt), the popular, and deadly, leader of one of the most powerful gangs in the DMZ. He wants to rule this new world and will stop at nothing to secure that outcome.

The drama will examine the stark political and cultural divide in American society, where Alma must contend with the gangs, militias, demagogues and warlords that control this lawless no man’s land. In doing so, she becomes the unlikely source of what everyone there has lost…hope.

Ariel will play the series regular role of Nico, a foul-mouthed scavenger with a hankering for mischief.

Gallegos will play Cesar, a ruthless and devoted consigliere who’ll stop at nothing to secure his gang’s authority in the DMZ.

Feliz will play Carmen, the fearless and fiery partner to the biggest bad in the DMZ, and a critical source of power and community in her native Spanish Harlem.

They join previously announced cast members Hoon Lee, Jordan Preston Carter and Freddy Miyares.

DMZ is produced by DuVernay’s Array Filmworks in association with Warner Bros. Television.

Gallegos previous credits include Gang Related, American Sniper and Spider-Man 3.
