Castle Rock cancelled after two seasons
According to Deadline, the decision not to press ahead with a third season was made a while ago.

The Stephen King anthology series Castle Rock has been cancelled after two seasons.
Set in the titular Maine town, Castle Rock told its own original story which featured many of the characters and themes from King’s novels.
Season one followed lawyer Henry Deaver (André Holland) as he returns to his hometown after a call from the local sheriff (Scott Glenn). A mysterious prisoner known as The Kid (Bill Skarsgård) has been found in an abandoned wing of Shawshank Penitentiary and has asked for Deaver by name.
Its second season went on to explore the feud between the Merrill clan led by Pop (Tim Robbins). A version of one of King’s most famous characters was also introduced, a younger Annie Wilkes (Lizzie Caplan) the psychopathic nurse from Misery.
Melanie Lynskey, Jane Levy, Sissy Spacek, Elsie Fisher, Paul Sparks, Barkhad Abdi and Yusra Warsama also star.
Castle Rock was created by duo Sam Shaw and Dustin Thomason with J.J Abrams and King serving as executive producers.
The news may be disappointing for King fans but there’s plenty more of his adaptations on the way.
The Stand, which is widely considered to be King’s best novel, a post-apocalyptic series which sees survivors of a deadly flu pandemic battling against evil forces is due to premiere in December and a The Shining spinoff titled Overlook Hotel is also in the works.
Both seasons of Castle Rock are available to stream on Starz Play here in the UK which is available as its own separate streaming service or as an add on channel to Amazon Prime.
