Beyond its brah-tastic Los Angeles setting, ‘The Walking Dead’’s upcoming “companion series” spinoff hasn’t given the clearest picture of what to expect. That said, where previously we learned ‘The Last Airbender’ star Cliff Curtis would lead the ensemble, we now have our leading lady for the “Cobalt” spinoff, none other than ‘Gone Girl’ and ‘Deadwood’ star Kim Dickens.

Per Deadline, Recent ‘Sons of Anarchy‘ guest star Dickens will play high school guidance counselor Nancy, who has two children from a previous marriage (‘Harry Potter and the Half-Blood Prince’ star Frank Dillane and AMC pilot ‘Galyntine’’s Alycia Debnam Carey). In addition to her relationship with divorced teacher Sean Cabrera (Curtis), Nancy is described as looking like the girl next door, with a darkness to her and a troubled past that will come back to haunt the character.

‘Walking Dead’ executive producers Robert Kirkman, Gale Anne Hurd and David Alpert will all take part in the new L.A.-set series, tentatively titled “Cobalt,” while ‘Sons of Anarchy’ and ‘Low Winter Sun’ vet Dave Erickson will both co-write and executive produce, and Adam Davidson will direct the pilot. We know that the series won’t be set in Georgia, and will likely take place at an earlier portion of the zombie apocalype, but could potentially cross over with the main ‘Walking Dead’ cast in time. Series creator Kirkman even previously offered up a few thoughts as to what might bring the series together.

Well, what say you? Does ‘The Walking Dead’’s spinoff have you any more excited by its latest casting? Would ‘Fringe’’s Anna Torv had been better, following her earlier tests? Tell us what you want to see from the mysterious “Cobalt” spinoff below, and check back in 2015 for new episodes of ‘The Walking Dead’ on AMC!
