Earlier this year HBO confirmed that Colin Farrell and Vince Vaughn would take two of the lead roles in season two of ‘True Detectives,’ while an expected female role had yet to be cast. Now the network has confirmed that Rachel McAdams has been cast to play a significant role in the sophomore season.

It had been rumors for months now that HBO had auditioned and offered the role to McAdams, though the network did not confirm the casting until earlier today. Expected to join Colin Farrell and Vince Vaughn in the season is Taylor Kitsch, as the final and fourth lead in the series. Earlier reports indicate that McAdams beat out Jessica Biel and Malin Ackerman, though HBO has not commented publicly on those previous choices.

Justin Lin will direct the first two episodes of season two. The show’s creator, Nic Pizzolatto, is writing the second season. The location for season two will be California, as the plot involves three police officers and a former-criminal with a dark past, who comes under investigation after his business partner is murdered.

In the new season McAdams and Kitsch are expected to play cops, while Farrell also plays an officer but with connections to the mob. Vaughn will play the criminal-empire leader in question. Kelly Reilly was the only surprising announcement today that was long-rumored. She is set to play a former D-list actress named Jordan, who is the wife of Vaughn’s character.
