ABC is rounding out its cast for its 13-episode drama series The Black Box. Ditch Davey (Spartacus: War Of the Damned) has signed on for the role of Dr. Marc Bickman, a brilliant neurosurgeon, David Ajala (The Dark Knight) will play Will Van Renseller, a professional chef by trade and caretaker by nature, and Ali Wong (Savages) has signed on as Dr. Ina Lark, with Tasso Feldman added as a recurring. The Black Box, written/exec produced by Amy Holden Jones, centers on Elizabeth Black (Kelly Reilly), a world-renowned neuroscientist who appears to have it all but is constantly haunted by her own struggle with mental illness.
