The character from Sarah Paulson came from the book One Flew over the Cuckoo's nest by Ben Kesey from 1962, which was already adapted into a movie back in 1975. Next to Paulson, the cast further consists of Sharon Stone (Mosaic), Cynthia Nixon (Hannibal) and Finn Wittrock (American Horror Story). According to Murphy, it is a 'horrifyingly' talented cast.
