The book "One Flew Over the Cuckoo's Nest" takes its title from a nursery rhyme. The first three and last lines are from the book, representing the thoughts of the schizophrenic narrator, Chief Bromden. The "cuckoo" refers to insane people, and "flying over the cuckoo's nest" means going too far or leaving the nest. It's also known that cuckoos lay eggs in other birds' nests and push out the others.
The 1975 movie by Milos Forman, starring Jack Nicholson as Randle Patrick McMurphy, was the second film to win all five major Academy Awards. Despite the movie's faithfulness to the book, the emotion and impact are different. Nicholson's performance added a comedic taste, perhaps diluting the book's message about mental wards as instruments of oppression.
The character of McMurphy, sane yet confined, is the first irony. Nurse Mildred Ratched, or Big Nurse, is the second irony. The setting is not as harsh as in other movies, and the patients have some freedoms. The story shows their power struggles, and the ending is tragic, but may not be meant to offer a resolution.
The book was a product of Ken Kesey's experience working at a mental health facility. The narration by Chief Bromden, an unreliable narrator due to his schizophrenia, makes the book unique. Without the insanity and scattered prose, the novel might not have had the same impact. Time Magazine included it in its "100 Best English-language Novels," an achievement Kesey deserves regardless of the movie's awards.
For its shocking revelation and brilliant narrative, reading this book is a spine-tingling experience.
