Castle Rock as of now has not been renewed for season 3. Craig Erwich, who is the Sr. VP, Head of Content for Hulu has said that Hulu has at present made no decisions for season 3.
The showrunner Dustin Thomason at present is in no hurry to bring back the show for a third season. Dustin and his partner, Sam Shaw have some plans ready as to what they want to follow in the upcoming season. They have an idea for which Stephen King character they want to explore in the upcoming season.
Thomason remarked in an interview that: “The plan was always to have an interconnected set of stories and, while every season would be its own launching point, there would be this fabric of Stephen’s multiverse, if you will, that always bubbled beneath it, and unity to the stories that existed.”
The showrunners hence are keen to maintain a continuity with the previous seasons. The expansion of the series will be done in a planned manner so that the viewers will “start to feel that there was a plan from the beginning.”
While the renewal of the show for the second season was brought along during the premiere of the first season, season 3 has not received any renewal yet. This might also have happened in the wake of the ongoing coronavirus pandemic.
Who will return to the third season of Castle Rock?
It is not yet officially announced who will return to the cast of Castle Rock for season 3 yet. But according to the finale of season 2, we can expect the return of Bill Skarsgard as The Kid.
Bill Skarsgard character has maintained a continuation between the first and second seasons. Hence we can expect his character to carry on to the third season.
Lizzy Caplanb would also probably reprise her role as Annie Wilkes.
When will the third season of Castle Rock premiere?
The first season of Castle Rock was released in the month of July 2018. The second season was released a year later in October of 2019. As of now, since the series has not been greenlit the premiere date will be probably pushed to late 2021.
Till then you can catch up with the first two seasons of Castle Rock on Hulu.
