TNT has given a six-episode order to L.A. Noir, the period-crime drama that reunites ousted Walking Dead showrunner Frank Darabont with his former stars Jon Bernthal and Jeffrey DeMunn.

Based on John Buntin’s acclaimed 2009 book L.A. Noir: The Struggle for the Soul of America’s Most Seductive City, the series chronicles the true-life battle between former police chief William Parker and mobster Mickey Cohen for control of Los Angeles in the 1940s and ’50s. The network describes the series as a fast-paced crime drama set in “a world of glamorous movie stars, powerful studio heads, returning war heroes, a powerful and corrupt police force and an even more dangerous criminal network determined to make L.A. its West Coast base.”

The official announcement, which arrives courtesy of Entertainment Weekly and Deadline, confirms a cast that also includes Jeremy Strong, Neal McDonough, Milo Ventimiglia and Ron Rifkin, with Simon Pegg in a guest role. Here's the official description:

This new series tells the true story of a decades-long conflict between the Los Angeles Police Department, under the determined leadership of Police Chief William Parker, and ruthless criminal elements led by Mickey Cohen, a one-time boxer who rose to the top of L.A.’s criminal world. The new drama stars Jon Bernthal (The Walking Dead) as Joe Teague, an ex-Marine now working as an LAPD cop in an era rampant with police corruption. Jeffrey DeMunn (The Walking Dead, The Shawshank Redemption) plays Det. Hal Morrison, who heads up the LAPD’s new mob squad, with Jeremy Strong (The Happening, Lincoln) as Det. Mike Hendry, Morrison’s second in command. Neal McDonough (Captain America, Desperate Housewives) is Capt. William Parker, Teague’s boss who is determined to weed out corruption and bring down Mickey Cohen. And Milo Ventimiglia (Heroes) plays Ned Stax, who fought alongside Teague during World War II but who now works as a lawyer with connections to the mob. In the pilot, Simon Pegg (Star Trek, Shaun of the Dead) guest-stars as Hecky Nash, a third-rate comedian and mob hanger-on.
