Rachel McAdams confirmed to star on 'True Detective' LOS ANGELES, Nov. 24 (UPI) -- Rachel McAdams has officially joined the cast of True Detective. The 36-year-old actress will portray Detective Ani Bezzerides on season two of the HBO series. Taylor Kitsch and Kelly Reilly are also confirmed for roles alongside previously announced stars Colin Farrell and Vince Vaughn. True Detective season two will take place in California, and follow Ani Bezzerides (McAdams), an ethical but troubled sheriff's detective, Ray Velcoro (Farrell), a compromised detective beholden to a mobster, Frank Semyon (Vaughn), a career criminal whose business partner is murdered, Paul Woodrugh (Kitsch), a war veteran and motorcycle officer and Jordan Woodrugh (Reilly), Frank's wife and a former D-list actress. True Detective premiered on HBO in January. The series follows an anthology format, so season one stars Matthew McConaughey, Woody Harrelson and Michelle Monaghan will not return. Season two is scheduled to debut in 2015, and will reportedly not be as dark as the first season. McAdams is known for portraying Regina George in Mean Girls, and Allison "Allie" Hamilton in The Notebook. The actress also appeared in Wedding Crashers alongside Vaughn and Sherlock Holmes with Reilly, and is attached to Southpaw and Spotlight.
