“This guy’s a scamp who knows he’s irresistible to women and, in reality, he expects Nurse Ratched to be seduced by him… This is his tragic flaw. This is why he ultimately fails. I discussed this with Louise* – I discussed it only with her. That’s what I felt was actually happening with that character. It was one long, unsuccessful seduction which the guy was so pathologically sure of.”
(Jack Nicholson about McMurphy in Jack Nicholson, the Unauthorised Biography by Barbara & Scott Siegel, 1990)
* Louise Fletcher – Nurse Ratched in the film version.
