Sources tell Variety HBO has offered McAdams the part opposite Colin Farrell and Vince Vaughn.
Though HBO recently announced Farrell and Vaughn as the show’s leads, sources say fans could have a similar response to the female lead as they did to Matthew McConaughey’s part as Rust Cohle in season 1.
Several other actresses have been considered for the part, including Jessica Biel and Malin Akerman, but McAdams has been seen as the front-runner for the past few weeks. HBO could not immediately be reached for comment.
McAdams is expected to play cops alongside Farrell, while Vaughn plays the crime boss whose empire is threatened when his partner is murdered.
It came down to scheduling, as insiders tell Variety McAdams was about to start filming “Spotlight,” the drama revolving around the Catholic Church sex scandal uncovered by the Boston Globe, and it was unknown whether dates could be worked out for McAdams to do that film and “True Detective.” Sources say that in the past 24 hours, a deal was worked out where the actress could do both projects.
