Almost everyone can agree that the second season of True Detective [1] was a bust. With such a successful first season and a disappointing follow-up, all eyes have now turned to season three [2]. This time around, Nic Pizzolatto will serve as writer and showrunner, and we already have a pretty enticing plot: we'll follow "a macabre crime in the heart of the Ozarks and a mystery that deepens over decades and plays out in three separate time periods." With a great creative team and a solid story, the third time might just be the charm for the floundering series. To add even more confidence to this installment, True Detective has complied a pretty star-studded cast. Check out everyone who's already signed on to brave the latest deadly conundrum.

Mamie Gummer as Lucy Purcell

Mamie Gummer, daughter of Meryl Streep [3], is the latest addition to the cast [4]. Gummer's character Lucy is "a young mother of two at the center of a tragic crime."

Stephen Dorff as Roland West

Dorff joins as an Arkansas State investigator [5] named Roland who is partners with Wayne Hays (Mahershala Ali). When it comes to his journey, Roland's "life and career [are] influenced over three decades by a baffling crime."

Mahershala Ali as Wayne Hays

Ali was the first star to join the cast [6] of the third season. He's playing Wayne Hays, a detective from northwestern Arkansas.

Carmen Ejogo as Amelia Reardon

Ejogo joined in late 2017 [7] as Amelia, an Arkansas schoolteacher with a connection to two missing children in 1980.

Scoot McNairy as Tom

Back in January, HBO added McNairy to the cast [8] as Tom, "a father who suffers a terrible loss that ties his fate to that of two state police detectives over 10 years."
