The friends are attached to star in True Detective, a potential anthology series currently being shopped to cable networks, The Hollywood Reporter has confirmed.
The duo would star as detectives Rust Cohle (McConaughey) and Martin Hart (Harrelson) whose lives become entangled while searching for a serial killer in Louisiana.
The project is being eyed as a potential eight-episode first season with following seasons replacing the cast and story — a similar format that FX has employed for its freshman hit American Horror Story from Glee co-creators Ryan Murphy and Brad Falchuk.
Nic Pizzolatto penned the project with Jane Eyre‘s Cary Fukunaga attached to direct all eight installments. Management company Anonymous Content — who represents Pizzolatto and Fukunaga — developed the project and will produce. The company’s Richard Brown, Steve Golin and Brad Dorros will executive produce.
For McConaughey, the project would mark his first series regular commitment. Harrelson, meanwhile, would return to the small-screen with his first series regular gig following his run as the clueless but lovable Woody Boyd on Cheers.
McConaughey and Harrelson are repped by CAA.
