HBO’s Lovecraft Country has added Michael K. Williams to its cast.

He joins Jonathan Majors, Jurnee Smollett Bell, Wunmi Mosaku, Elizabeth Debicki, Aunjanue Ellis and Courtney B. Vance in the series from Misha Green, Jordan Peele and JJ Abrams.

Williams will play Montrose Freeman who is Atticus’ father. The character description: Hard headed and secretive, he’s always believed you can’t live in a fantasy world, which is why he despises his son’s pulp novels. Most of the books on his shelf are nonfiction, history and political theory. The guys at the local bar call him a communist, but today we’d just call him conscious.

This puts Williams back at HBO, where he starred in The Wire, Boardwalk Empire and The Night Of. On the TV front, he’ll be seen next in Ava DuVernay’s event series Central Park Five at Netflix.

Underground showrunner Green is the scriptwriter and executive produces with Peele through his Monkeypaw Productions and J.J. Abrams through Bad Robot. Ben Stephenson and David Knoller also executive produce. Yann Demange is directing the pilot and executive produces. Warner Bros Television is the studio.

Focusing on members of two black families and described as “a devastating kaleidoscopic portrait of racism,” here’s the story Lovecraft Country tells, courtesy of the publisher: Chicago, 1954. When his father Montrose (Williams) goes missing, 22-year-old Army veteran Atticus Turner (Majors) embarks on a road trip to New England to find him, accompanied by his Uncle George—publisher of The Safe Negro Travel Guide—and his childhood friend Letitia (Smollett-Bell). On their journey to the manor of Mr. Braithwhite—heir to the estate that owned one of Atticus’s ancestors—they encounter both mundane terrors of white America and malevolent spirits that seem straight out of the weird tales George devours. At the manor, Atticus discovers his father in chains, held prisoner by a secret cabal named the Order of the Ancient Dawn—led by Samuel Braithwhite and his son Caleb—which has gathered to orchestrate a ritual that shockingly centers on Atticus. And his one hope of salvation may be the seed of his—and the whole Turner clan’s—destruction.

The series is due in 2019.
