Hulu’s Stephen King and J.J. Abrams anthology series Castle Rock is shaping up to have one of the most exciting casts on TV. From Andre Holland to Scott Glenn and Melanie Lynskey, the psychological-horror series is jam-packed with fantastic talent. And now a LOST alum is joining the ranks.

John Locke, a.k.a. Terry O’Quinn, is the latest actor headed to Castle Rock. That means a LOST reunion is on the way with Abrams, who will serve as executive producer on the show alongside King. Deadline has the scoop on O’Quinn’s character Dale Lacy, described as “a pillar of the community” in Castle Rock, the fictional Main town that’s appeared across numerous King works. The anthology series will take place in the King multi-verse and unite the worlds of his novels and short stories. Here’s the full description:

A psychological-horror series set in the Stephen King multiverse, Castle Rock combines the mythological scale and intimate character storytelling of King’s best-loved works, weaving an epic saga of darkness and light, played out on a few square miles of Maine woodland. The fictional Maine town of Castle Rock has figured prominently in King’s literary career: Cujo, The Dark Half, IT and Needful Things, as well as novella The Body and numerous short stories such as Rita Hayworth and The Shawshank Redemption are either set there or contain references to Castle Rock. Castle Rock is an original suspense/thriller — a first-of-its-kind reimagining that explores the themes and worlds uniting the entire King canon, while brushing up against some of his most iconic and beloved stories.

O’Quinn joins The Leftovers‘ Glenn, playing retired sheriff Alan Pangborn, Lynskey as Molly Strand, and It star Bill Skarsgard in a mystery role. The cast also includes Sissy Spacek as Ruth Deaver, the estranged adoptive mother of Holland’s Henry and Jane Levy‘s Jackie, who considers herself an historian of Castle Rock. There’s a ton of potential territory to cover with a project as ambitious as this, so stay tuned as more details come out.
