HBO has confirmed that Rachel McAdams (‘Southpaw,’ ‘A Most Wanted Man’), Taylor Kirsch (‘The Normal Heart,’ ‘John Carter’) and Kelly Reilly (‘Calvary,’ ‘Flight’) have the joined the cast of the second season of the Nic Pizzolatto created crime drama ‘True Detective.’

They join the previously cast Colin Farrell and Vince Vaughn on the eight-episode, hour-long drama which centres on “three police officers and a career criminal who must navigate a web of conspiracy in the aftermath of a murder.”

Farrell will be playing Ray Velcoro, a character described as “a compromised detective whose allegiances are torn between his masters in a corrupt police department and the mobster who owns him.”

Vaughn is playing Frank Semyon, a career criminal in danger of losing his empire when his move into legitimate enterprise is upended by the murder of a business partner.

McAdams, who-starred with Vaughn in ‘Wedding Crashers,’ will play Ani Bezzerides. A detective with the Ventura County Sheriff’s department, Bezzerides is said to have “uncompromising ethics” that “put her at odds with others and the system she serves.”

Kitsch will take the role of Paul Woodrugh, a war veteran and motorcycle officer for the California Highway patrol who is running from a difficult past, and is also involved in a scandal that never happened.

Reilly is set to play Jordan, wife to Vaughn’s character, a former D-list actress who is a full partner in his enterprises and ambitions.

Deadline has word on supporting players, with Michael Irby, Abigail Spencer , Leven Rambin, Riley Smith, Lolita Davidovich, James Frain, Adria Arjona, Chrsitian Campbell, Michael Hyatt and Yara Martinez on board for recurring roles.

Filming is underway in California with Pizzolatto writing and ‘Fast & Furious’ helmer Justin Lin on board to direct the first two episodes.
