Michelle Monaghan Joins Matthew McConaughey, Woody Harrelson Drama ‘True Detective’

Michelle Monaghan has joined Matthew McConaughey and Woody Harrelson’s HBO drama True Detective.

The eight-episode series follows two detectives, Rust Cohle (McConaughey) and Martin Hart (Harrelson) during their 17-year hunt for a serial killer in Louisiana. A 1995 murder is reopened in 2012, and the series will be interlaced with the original investigation and the detectives’ testimony almost two decades later.

Monaghan will play Maggie Hart, Martin’s wife, who “makes a hard decision that has long-reaching and devastating consequences,” according to TVLine.

The series will be directed by Cary Fukunaga, whose credits include Sin Nombre and Jane Eyre. It will be written by Nic Pizzolatto, who wrote two episodes of the The Killing.

If the series goes beyond one season, each subsequent season will feature a new mystery and a different case.

Monaghan has recently completed three films: Better Living Through Chemistry with Olivia Wilde and Sam Rockwell, Gus with Radha Mitchell and Jon Dore, and Penthouse North with Michael Keaton and Andrew W. Walker. She previously appeared in Mission Impossible: Ghost Protocol with Tom Cruise and Jeremy Renner, Source Code with Jake Gyllenhaal and Vera Farmiga, and Due Date with Robert Downey Jr. and Zach Galifianakis.

Monaghan’s True Detective co-star, Woody Harrelson, is currently filming The Hunger Games: Catching Fire. He plays Haymitch Abernathy, the only living victor from District 12, and the mentor to Katniss Everdeen (Jennifer Lawrence) and Peeta Mellark (Josh Hutcherson).

McConaughey is currently filming Dallas Buyer’s Club, which is loosely based on the life of Ron Woodroof, who was diagnosed with HIV/AIDS and given 30 days to live, and begins smuggling non-toxic, anti-viral drugs from all over the world.
