Clive Barker has joined the Exec Producing team of HBO’s developing series adaptation of his classic horror franchise, Hellraiser. Deadline broke in April that Halloween helmer David Gordon Green is on board to direct the initial episodes.

The series will be written by Mark Verheiden (Battlestar Galactica) and Michael Dougherty (Trick r’ Treat) with Verheiden running the show. They will be executive producers alongside Farah Films’ Dan Farah (Ready Player One), Vertigo Entertainment’s Roy Lee (IT), Rough House Pictures partners Green, Danny McBride Jody Hill and Brandon James (Halloween), as well as Panacea’s Eric Gardner, Lawrence Kuppin, David Salzman, and Marc Toberoff. Farah Films exec Andrew Farah, and Adam Salzman will also serve as co-exec producers.

Based on the Hellraiser horror franchise and Clive Barker’s novel The Hellbound Heart, the series is planned as an elevated continuation of the existing Hellraiser mythology. The franchise has been a global pop-culture phenomenon for over thirty years and one of the scariest. Aside from 10 films, the franchise has also spawned a book anthology, comic books, and global merchandise apparel.
