The actor Sarah Paulson has appeared in “12 Years a Slave,” “The People v. O. J. Simpson,” and eight seasons of Ryan Murphy’s “American Horror Story.” Now she’s starring in a new Murphy production—the series “Ratched,” which premieres on Netflix next month. It’s a macabre, over-the-top fantasy describing the origin story of Nurse Ratched, the heartless, possibly not-quite-human villain of Ken Kesey’s novel “One Flew Over the Cuckoo’s Nest.” Personified by Louise Fletcher in the 1975 film, Nurse Ratched is considered one of the great modern antiheroes. “I do think any character you play, particularly the ones that, on the surface, seem difficult, angry, monstrous—a lot of people don’t like to investigate that kind of stuff,” Paulson told the staff writer Michael Schulman at the 2019 New Yorker Festival. “But, to me, I think, it’s sort of our job.”
