True Detective Season 2 Rounds Out Its Cast! Find Out Who's Joining the HBO Drama

HBO's critically loved drama will have a few new faces next season

And the True Detective season two casting news just keeps on coming!

After Taylor Kitsch broke his own casting announcement earlier this week (and Matthew McConaughey confirmed it!), four more names have become attached to HBO's critically loved drama for the second season.

A source confirms to E! News that Black Box alum Kelly Reilly has landed a series regular role, and Almost Human's Michael Irby, Suits star Abigail Spencer and The Tomorrow People's Leven Rambin have all scored recurring roles.

These four will join the previously reported True Detective season two stars Colin Farrell, Vince Vaughn and Kitsch, while Rachel McAdams is rumored to be near a deal to play the fourth and final lead role. Our source tell us both Reilly and Spencer were in contention for McAdams' lead role, but the network wanted to go with a more well-known name instead.

Season two revolves around three police officers and a career criminal who must navigate a web of conspiracy in the aftermath of a murder.

Vaughn will play Frank Semyon, a career criminal struggling to move in a legit direction. Farrell will play Ray Velcoro, a "compromised detective." Kitsch is set to play a detective, and McAdams, if cast, will play the third detective.

Reilly's character is described as the "self-possessed Morgan," while Irby will play McAdams' partner, Elvis. Rambin will play a beautiful woman with a history of drug problems, and Spencer will portray the survivor of a sexual attack.

Justin Lin, who recently helmed the Scorpion pilot, will direct the first two episodes of the eight-episode second season, written by creator Nic Pizzolatto. Production will begin later this fall in California.

Deadline first reported the casting news.
