Season 2 of Castle Rock adds Lizzy Caplan in a major role as a young Annie Wilkes, a nurse and superfan battling to overcome mental health issues.
Caplan will be joined by Oscar winner Tim Robbins who will play as Reginald “Pop” Merrill, the crime lord from the King story The Sun Dog which was set in Castle Rock. Others who will be part of the cast are Elsie Fisher, Garrett Hedlund, Barkhad Abdi, Yusra Warsama, and Matthew Alan.
“We want to surprise viewers with the ways in which the stories intersect. Just as the places the characters pop up in very unexpected ways throughout the books, that’s the kind of anthology that we would like to tell,” explained showrunner Dustin Thomason in an interview with The Hollywood Reporter. “One of the things about the King universe, or multiverse, is that some very strange things can happen when it comes to the ways that the stories unfold, and hopefully there will be surprises along the way in terms of how the anthology works in that way.”

Season two will center around Annie Wilkes, Stephen King’s nurse from hell, who gets waylaid in the town of Castle Rock as a feud between warring clans comes to a boil.
Castle Rock, which premiered in July, 2018, is Hulu’s second series from the King universe. The streamer reported that within its first day of launch, Castle Rock became the most successful first season Hulu Original when considering consumption and reach.
