Arquette has been cast in a multi-episode arc. Character details are being kept under wraps.
Ratched begins in 1947 and follows Ratched (Paulson)'s journey and evolution from nurse into the full-fledged monster we know from One Flew Over the Cuckoo's Nest. The series will track her murderous progression through the mental health care system.
