Take a look at the first footage from this 1940s L.A. crime drama starring Jon Bernthal and Jeffrey DeMunn, then read the press released for more details.

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: The First Avenger, Desperate Housewives), Edward Burns (Entourage), Gregory Itzin (24), Robert Knepper (Prison Break), Milo Ventimiglia (Heroes), Alexa Davalos (Clash of the Titans, Stephen King's The Mist) and Jeremy Luke (Don Jon). Also serving as executive producers on the series are Michael De Luca (The Social Network) and Elliot Webb (Alpha House).

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 opens in post-war Los Angeles, home to glamorous movie stars, powerful studio heads and returning war heroes. But it's also a city caught between a powerful and corrupt police force and an even more dangerous criminal network determined to make L.A. its West Coast base. Los Angeles Police Chief William Parker (Neal McDonough) has made it his mission to free the city of criminals like Ben "Bugsy" Siegel (Edward Burns) and Mickey Cohen (Jeremy 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.

To carry out his sweep of organized crime, Parker sets up a new mob task force within the LAPD. Headed by Det. Hal Morrison (Jeffrey DeMunn), the task force includes Det. Joe Teague (Jon Bernthal), an ex-Marine who holds his cards close to his chest.

Mob City is produced by TNT Originals. Working on the series with Darabont, De Luca and Webb are co-executive producers Alissa Phillips and Dana Renee Ashmore, with Paul Bernard serving as producer.
