Jon Seda will be officially sinking into his new project in September…

NBC has set the fall premiere date for its new drama series La Brea, starring the 50-year-old Puerto Rican actor, for Tuesday, September 28 at 9:00 pm ET.

In La Brea, written by David Appelbaum, when a massive sinkhole mysteriously opens in Los Angeles, it tears a family in half, separating mother and son from father and daughter. When part of the family find themselves in an unexplainable primeval world, alongside a disparate group of strangers, they must work to survive and uncover the mystery of where they are and if there is a way back home.

Seda plays Dr. Sam Velez. The father of a teenage girl, he carries himself like the general of an Army.

In addition to Seda and Zea, the cast also includes Nicholas Gonzalez, Lily Santiago, Vanessa Buckley and Chloe de los Santos.

Universal Television, a division of Universal Studio Group, is the studio, producing with Keshet Studios.
