Kai Lennox (The Unusuals), Dale Dickey (Leave No Trace), Austin Hébert (Jack Reacher: Never Go Back) and Omar Maskati (Better Call Saul) are set for recurring roles in Unbelievable, an eight-episode Netflix limited series from Erin Brockovich writer Susannah Grant, CBS TV Studios, studio-based producers Sarah Timberman and Carl Beverly (Masters of Sex, Elementary) and Katie Couric.

Co-written by Grant, who will serve as showrunner, Michael Chabon (John Carter) & Ayelet Waldman (Applebaum), Unbelievable is based on The Marshall Project and ProPublica Pulitzer Prize-winning December 2015 article, “An Unbelievable Story of Rape,” written by T. Christian Miller and Ken Armstrong, and the “This American Life” radio episode about the same case, “Anatomy of Doubt.” It tells the true story of Marie, a teenager who was charged with lying about having been raped, and the two female detectives who followed a twisting path to arrive at the truth.

Details of their characters are not being revealed. They join previously cast Toni Collette, Merritt Wever, Kaitlyn Dever and Danielle MacDonald.

Grant, Chabon, Waldman, Timberman, Beverly and Couric executive produce.

Dickey can currently be seen in Debra Ganik’s new film Leave No Trace, Ganik’s first film since Winter’s Bone, for which Dickey won an Independent Spirit Award. She also recurs on Claws. Dickey is repped by BRS/Gage Talent Agency.
