After being fired from “The Walking Dead” following the first season of the AMC zombie drama he developed for television, “The Shawshank Redemption” director Frank Darabont went right back to work on another small screen project, this time for TNT. “Mob City,” formerly called “L.A. Noir” and “Lost Angels,” is an “event series” about cops and mobsters in Los Angeles in the 1940s and ’50s, based on John Buntin’s book “L.A. Noir: The Struggle for the Soul of America’s Most Seductive City.” “Walking Dead” alum Jon Bernthal, Jeremy Luke, Milo Ventimiglia, Jeffrey DeMunn, Alexa Davalos and Neal McDonough are in the cast, as is Edward Burns as Bugsy Siegel and Simon Pegg, who you get a glimpse of in the stylized trailer below, in a guest role. “Mob City” premieres Wednesday, December 4th — does it look promising? Or like too much of a familiar thing?
