With production set to begin early next year on The Walking Dead's highly-anticipated companion series entitled Cobalt, TV Line has learned that the spin-off will be set in Los Angeles. It isn't known at this time if the series will actually shoot in Los Angeles, or if another city such as Vancouver will double for the City of Angels at this time. AMC has not confirmed anything regarding the series except that the pilot episode has been ordered.

Cobalt will be set during The Walking Dead's zombie apocalypse, but it will take place clear across the country in L.A., thousands of miles from Rick (Andrew Lincoln) and his crew of survivors in Atlanta. It has been rumored that the spinoff will be a prequel series of sorts, chronicling the early days of the zombie virus that spreads throughout the nation. But those details have yet to be confirmed. Cliff Curtis was cast earlier this month as the male lead, a teacher in his 40s. A casting breakdown from September revealed this character will be named Sean Cabrera, and is trying to do right by the people in his life.

Other confirmed cast members include Frank Dillane as Nick Tompkins, a troubled teenager with a drug problem, and Alycia Debnam Carey as Nick's sister Ashley, who is much more ambitious than her brother. Other characters still yet to be cast are Nick and Ashley's mother Nancy, a thirtysomething single mom and guidance counselor who has an edge to her, Sean Cabrera's rebellious teenage son Cody, and Andrea Chapman, a former flower child in her 40s. Robert Kirkman co-created the show with Dave Erickson, with Adam Davidson directing the pilot episode.
