Rachel McAdams is reportedly in talks to join the cast of True Detective for the acclaimed drama's second season.

Earlier this week, it was confirmed that Irish actor Colin Farrell landed a lead role in the cult HBO series, alongside McAdams' Wedding Crashers co-star Vince Vaughn.

According to Deadline and Variety, the 35-year-old Canadian could be playing an indulgent sheriff called Ani Bezzerides.
