The Hulu drama, already renewed for a second season, is the latest entry into television's increasingly expanding horror anthology game. Details about the show's anthological approach have been left under wraps, however. Will Castle Rock follow in the American Horror Story mold, for example, insofar as bringing series regulars back season after season, albeit in different roles?

"We certainly love the fact that Kathy Bates got to play two of the most iconic Kingian female characters," says Thomason, "and the oddness of knowing that she inhabits a couple of parts of that universe. We certainly have been incredibly fortunate and amazed by the excitement of having who we consider to be the alpha and omega of the King actors in [It star Bill Skarsgård] and [Carrie star Sissy Spacek] this season."

As for whether Castle Rock would ever return to the story of Henry Deaver in a future season, or if they view the current mystery fully resolved, Thomason offered, "We always took the approach that Steve does in his work, which is that we feel that he has been building this grand library of characters and stories that often bend back on themselves in unexpected way. You look at Father Callahan in Salem's Lot and The Dark Tower, for example. I think the idea of returning to Father Callahan was something that had percolated in Steve's mind long before we saw him in The Dark Tower. In that same spirit, I think we feel like the time and place would have to be right, and we would hope to do it in just as unexpected a way as Steve does it with his characters."
