Amber Tamblyn has signed onto CBS' new fantasy-drama 'Babylon Fields,' says the Hollywood Reporter. The series is a comedy-drama about the dead rising from the grave and attempting to return to their normal lives. The former 'Joan of Arcadia' star plays a young woman who was abused by her father and conspired to kill him with her mother, only to find out he's back from the dead. Michael and Gerald Cuesta and Michael Atkinson are running this zombie series, which may see the light of day as early as Fall.
