With his new TNT series “Mob City,” “The Shawshank Redemption” director Frank Darabont takes another look at a gritty, post-war corruption — albeit on the streets this time, instead of in the jail cells.

Based on John Buntin’s novel “L.A. Noir: The Struggle for the Soul of America’s Most Seductive City,” the series formerly titled “Lost Angels” covers the seedy overlap between early Hollywood, the mafia and a struggling police force. “Justified’s” Neal McDonough plays Los Angeles Police Chief William Parker, who is tasked with keeping the streets safe from wiseguy thugs like Bugsy Siegel (Ed Burns) and Mickey Cohen (Jeremy Luke).

The country’s history of noir and corruption has always been a favorite film and TV trope. “Breaking Bad” writer George Mastras is adapting Dean Unkefer’s autobiographical “90 Church: The True Story Of The Narcotics Squad From Hell” into a film for Universal. Sean Penn played mobster Cohen in last winter’s “Gangster Squad,” a film Variety critic Peter Debruge called “an impressively pulpy underworld-plunger.”

“Mob City” premieres December 4.
