The anthology, from J.J. Abrams and Stephen King, will put a new spin on Kathy Bates' famed nurse Annie Wilkes, with Lizzy Caplan set to take on the leading role in the sophomore season.
Season two will explore a feud between warring clans that comes to a boil when budding psychopath Annie Wilkes, King's nurse from hell, gets waylaid in Castle Rock.
Joining Caplan — one of pilot season's most in-demand actresses — are Tim Robbins (Here and Now), Eighth Grade breakout Elsie Fisher, Garrett Hedlund (Tron, Mosaic), Barkhad Abdi (Captain Phillips, Blade Runner 2049), Yusra Warsama (Call the Midwife) and Matthew Alan (Lovecraft Country, 13 Reasons Why).
