Here’s a running list of all the Stephen King Easter eggs embedded in Castle Rock that we found.
Alan Pangborn The only character directly taken from King’s books to appear so far on Castle Rock is Alan Pangborn, who was the sheriff of Castle Rock, Maine, in The Dark Half and Needful Things.
Hulu’s new series Castle Rock is set in the “Stephen King multiverse,” which means that while it’s not an adaptation of any Stephen King story, it’s connected to a whole bunch of them, not unlike how King references his other stories in his fiction.
Nan’s Luncheonette It’s burned down by the time of Castle Rock, but it was around for IT and Needful Things.
