Hulu just released a new teaser for its upcoming drama Castle Rock that hints at how the mysterious Maine town turned out the way it did. The series, created by J.J. Abrams’ Bad Robot Productions, is inspired by the interconnected Stephen King universe.

In the teaser, Lost’s Terry O’Quinn’s gentle voiceover describes the “original sin” of Castle Rock, a fictional town in which a number of King’s novels are set, including The Dead Zone, Cujo, and The Dark Half. Castle Rock will feature themes and characters from across King’s work, as well as a few new characters created just for the TV series and several actors from previous iterations of King adaptations, like Sissy Spacek (Carrie) and Bill Skarsgård (2017’s It), playing new roles.

The series will likely include plenty more references for King fans to uncover. The first season will be a self-contained story in which lawyer Henry Deaver (Andre Holland) returns to his hometown of Castle Rock to represent Skarsgård’s character, who is imprisoned at Shawshank Prison.

During New York Comic Con last fall, executive producer Dustin Thomason said Castle Rock’s second season will feature an entirely new cast and storyline. Its first season also stars Scott Glenn as Alan Pangborn, Spacek as Henry Deaver’s adoptive mother Ruth, and O’Quinn as town figurehead Dale Lacy, although Entertainment Weekly reports that he never appears on-screen.

The series will premiere on Hulu on July 25th.
