HBO says that Colin Farrell and Vince Vaughn will star in the second season of "True Detective."

The eight-episode drama series will begin production in California this fall, the premium cable channel said Tuesday.

Farrell will play a compromised detective, Ray, who is divided between his loyalty to his bosses in a corrupt police department and a mobster with a hold over him.

Vince Vaughn plays Frank, a criminal whose move into legitimate business is disrupted by a business partner's murder.

HBO had a critically acclaimed hit with the first season of "True Detective," which starred the Emmy-nominated Matthew McConaughey and Woody Harrelson.

The air date for the second season was not announced.
