Rachel McAdams and Taylor Kitsch will join Vince Vaughn and Colin Farrell in the lead roles of HBO's second season of its True Detective franchise.

McAdams will portray Ani Bezzerides, a Ventura County detective with "uncompromising ethics," while Kitsch is Paul Woodrugh, a war veteran and motorcycle highway patrol officer with a painful life.

For his part, Farrell is on board as Ray Velcoro, a detective torn between mobsters and his corrupt department, and Vaughn is this season's criminal, Frank Semyon. Kelly Reilly is Seymon's wife, partner and "former D-list actress" Jordan.

Last season's highly decorated rookie run of True Detective showcased Matthew McConaughey, and Woody Harrelson in Emmy-nominated outstanding lead actor turns in a drama series. Like the show itself, both actors came up short with the Emmy crowd that favored the final season of AMC's Breaking Bad.
