Carmen Ejogo has joined the cast of “True Detective” season three.

Ejogo will star opposite the previously announced Mahershala Ali in the new installment of the HBO anthology drama. She will play Amelia Reardon, an Arkansas schoolteacher with a connection to two missing children in 1980. Ali is set to play Wayne Hays, a state police detective from Northwest Arkansas. The new season tells the story of a macabre crime in the heart of the Ozarks, and a mystery that deepens over decades and plays out in three separate time periods.

Ejogo will next be seen in Dan Gilroy’s “Roman J. Israel, ESQ.” alongside Denzel Washington. She currently stars on the second season of the Starz series “The Girlfriend Experience” for writer and director Amy Seimetz. Her credits include “Selma,” “It Comes at Night,” “Alien: Covenant,” “Fantastic Beasts and Where to Find Them,” and “Born to be Blue.” She recently wrapped shooting on “Fantastic Beasts: The Crimes of Grindelwald.” She is represented by WME, Anonymous Content, and Conway Van Gelder Grant.

Executive producers on season three of “True Detective” are Nic Pizzolatto, Scott Stephens, Matthew McConaughey, Woody Harrelson, Cary Joji Fukunaga, Steve Golin, Bard Dorros, and Richard Brown. Pizzolatto, the series creator, is serving as director, writer, and showrunner.
