The most interesting aspects of Louise Fletcher's performance as Nurse Ratched in Milos Forman's One Flew Over The Cuckoo's Nest, which I honestly never liked all that much (and this is from a guy who played Dr. Spivey in a Connecticut stage version of Ken Kesey's play): (1) Instead of being butch-bossy, she was subdued and icy; (2) the combination of those hazel eyes and that slightly opened mouth had a macabre effect; (c) the 1940s Ann Sheridan hair style said more about Ratched than anything she said or did in that film.
