Law & Order True Crime: The Menendez Murders continues to build out its ensemble.

James DuMont (Deepwater Horizon, Treme) has signed on for the first season of Dick Wolf's anthology series, The Hollywood Reporter has learned.

The eight-episode first installment of the anthology series is described as a "gripping in-depth dramatization" of the famed murder case that took America by storm in the early 1990s. When brothers Lyle and Erik Menendez were tried on national TV for brutally killing their parents in Beverly Hills on Aug. 20, 1989, their story became a nationwide obsession. Law & Order True Crime: The Menendez Murders dives into the players, the crime and the media circus, detailing the day-to-day battles of the trial and unveiling the shocking truth of what really went down behind the scenes.

DuMont is set to play Brian Anderson, the older brother of the murdered matriarch Kitty Menendez. A man of Midwestern reserve, he attends a family memorial in a large hotel suite despite having had a troubled relationship with his dead sister.

After Kitty was murdered along with her husband Jose, Anderson dismissed allegations made by the brothers' defense team that they had been abused by their mother prior to her death — a key part of their defense strategy.

DuMont joins a cast that includes Edie Falco, Anthony Edwards and Julianne Nicholson, with Gus Halper and Miles Gaston Villanueva portraying the Menendez brothers.

DuMont's other credits include American Horror Story, Jurassic World and Steven Soderbergh's upcoming HBO movie Mosaic. He is repped by Media Artists Group and Buffalo 8 Management.

Ordered to series last July, Law & Order True Crime follows in the vein of true-crime scripted dramas like The People v. O.J. Simpson: American Crime StoryLaw & Order vet Rene Balcer serves as showrunner, while Lesli Linka Glatter (Homeland) will direct several episodes. The two will executive produce with Wolf, Peter Jankowski and Arthur W. Forney. Universal Television will produce in association with Wolf Films.

Law & Order True Crime: The Menendez Murders will air Tuesdays at 10 p.m. ET/PT this fall on NBC.
