(nee L.A. Noir), the new TNT series coming from The Walking Dead's original showrunner Frank Darabont, is kicking its promotional campaign into high gear ahead of its December 4 premiere date. The series, which stars The Walking Dead's Jon Bernthal and Jeffrey DeMunn alongside actor/filmmaker Edward Burns and Heroes alum Milo Ventimiglia, comes to TNT as the first new TV project from showrunner Darabont since he left AMC's hit zombie drama at the start of its second season. Most of those in the cast come from previous Darabont projects, including The Mist and The Shawshank Redemption. Check out the trailer, and the official description for the series, below. The epic battle between a determined police chief and a dangerous mobster inflames 1940s Los Angeles in TNT's eagerly anticipated television event Mob City. This powerful drama comes to TNT from Frank Darabont (The Walking Dead), who wrote and directed the pilot and serves as executive producer on the series. Mob City stars an exceptional ensemble cast that includes Jon Bernthal (The Walking Dead), Jeffrey DeMunn (The Walking Dead, The Shawshank Redemption), Neal McDonough (Captain America, Desperate Housewives), Ed Burns (Entourage), Gregory Itzin (24), Robert Knepper (Prison Break), Milo Ventimiglia (Heroes), Alexa Davalos (Clash of the Titans, The Mist) and Jeremy Luke (Don Jon). Based on the critically acclaimed book L.A. Noir: The Struggle for the Soul of America's Most Seductive City, by John Buntin, Mob City centers on Det. Joe Teague (Bernthal), an ex-Marine who holds his cards close to his chest. Teague has been assigned to a new mob task force headed by Det. Hal Morrison (DeMunn). The task force is part of a crusade by Los Angeles Police Chief William Parker (McDonough) to free the city of criminals like Ben "Bugsy" Siegel (Burns) and Mickey Cohen (Luke), the ruthless king of the Los Angeles underworld. Parker also won't hesitate to go after anyone from his own police force who sells out honor and duty for the sake of a big payout. Mob City is produced by TNT Originals. Also serving as executive producers on the series are Michael De Luca (The Social Network) and Elliot Webb (Alpha House). Alissa Phillips and Dana Renee Ashmore serve as co-executive producers, with Paul Bernard as producer.
