Former "The Walking Dead" showrunner Frank Darabont's event series at TNT, "Mob City" (formerly known as "Lost Angels" and "L.A. Noir"), will premiere on Dec. 4 at 10/9c.
Based on the John Buntin book "L.A. Noir: The Struggle for the Soul of America's Most Seductive City," the series chronicles the decades-long feud between the LAPD, led by then-Chief William Parker, and Mickey Cohen's West Coast gang in 1947 Los Angeles.
