Mob City, Mob, Mob City. Mob City is a new TNT special-event series by Frank Darabont, the director of The Shawshank Redemption and the showrunner for the first season of The Walking Dead. The six-episode series will tell the true story of the war against organized crime in post-WWII L.A. The cast includes The Walking Dead's Jeffrey DeMunn and Jon Bernthal, Ed Burns as Bugsy Siegel, and Jeremy Luke as Mickey Cohen (who Sean Penn recently played in Gangster Squad). The show premieres on December 4 and will sadly feature zero fancily dressed zombies.
