There’s probably a lot that you don’t know about this film, but today my aim is to change that…
Here are 21 Facts You Might Not Know about One Flew Over the Cuckoo’s Nest
1. Chosen for the role of Chief Bromden, Will Sampson, who was a Park Ranger in Oregon, was selected due to his unique combination of being the only Native American the casting department could locate and his remarkable size, which aligned with the character’s physical presence. The filming location happened to be near his place of work.
2. In subsequent interviews, Louise Fletcher revealed that she discovered methods to humanize Nurse Ratchet while still maintaining an unsympathetic demeanor. She ultimately concluded that Nurse Ratched genuinely cared for the patients and believed she was acting in their best interests. However, Fletcher perceived the character as misguided, succumbing to the intoxication of her own power.
3. Opting for a percentage of the profits instead of a nominal salary for a moderately budgeted film, Jack Nicholson’s decision proved lucrative as the movie went on to generate a substantial revenue, surpassing $120 million.
4. While filming, a crew member who was running cables inadvertently left a second-story window open at the Oregon State Mental Hospital. Consequently, an actual patient climbed through the bars, fell to the ground, and suffered injuries. The following day, The Statesman Journal in Salem, Oregon, highlighted the incident on the front page with the headline “One flew OUT of the cuckoo’s nest.”
5. Many of the extras in One Flew Over the Cuckoo’s Nest were authentic mental patients.
6. Louise Fletcher, distressed by the contrast between her character’s cold demeanor and the jovial atmosphere of the other cast members, took a bold step near the end of production. In an effort to dispel the notion that she was a “cold-hearted monster,” she removed her dress and stood in only her panties, expressing her emotional vulnerability to the rest of the cast.
6. One Flew Over The Cuckoo’s Nest achieved the rare distinction of winning all five major Academy Awards (Best Picture, Best Actor, Best Actress, Director, and Screenplay), a feat previously accomplished by It Happened One Night in 1934. This remarkable achievement wasn’t replicated until 1991 when The Silence of the Lambs also won all five major Oscars.
7. This film marked the film debuts Christopher Lloyd (Doc Brown from Back To The Future) and Brad Dourif (the actor who voices Chucky in the Child’s Play franchise).
8. Initially revealed in 1962 with Kirk Douglas set to star, One Flew Over The Cuckoo’s Nest underwent a prolonged 13-year development process. Actual filming commenced in January 1975 and spanned three months, taking place on location in Salem, Oregon, and its vicinity, as well as in Depoe Bay on the north Oregon coast.
9. The filmmakers chose to shoot the movie at the Oregon State Hospital, an authentic mental institution and the same setting as the novel. Although the hospital remains operational, the original structures featured in the film have since been demolished.
10. Miloš Forman, who fled Czechoslovakia following the Prague Spring, drew from his personal experiences living under Communist rule to create the oppressive atmosphere depicted in the mental hospital.
11. Under the emotional strain of a rigorous shooting schedule that kept him far from his future wife, Rhea Perlman, Danny DeVito devised a coping mechanism—creating an imaginary friend for nightly conversations. Fearing a potential erosion of his sanity, DeVito sought guidance from Dr. Brooks, who reassured him that as long as he could distinguish the character as fictional, there was no cause for concern.
12. A patient employed by the production company had struggled with a lifelong stutter. However, his involvement and responsibilities with the producers proved so inspiring that his stutter was ultimately overcome, marking a permanent resolution.
13. Louise Fletcher found her own performance so unsettling that she refrained from watching the film for several years.
14. Numerous cast members maintained their characters even between takes. When Jack Nicholson first arrived on set, he was taken aback by the authenticity of the rest of the cast, prompting him to dash outside and inquire, “Do they ever break character?”
15. In the original One Flew Over The Cuckoo’s Nest script, McMurphy was supposed to leap on a guard and kiss him upon his arrival at the hospital. However, during filming, director Milos Forman felt that the guard’s reaction was not strong enough.
He instructed Jack Nicholson to instead jump on the other guard. This unexpected change surprised the actor playing the second guard, and in certain versions, he can be observed punching Nicholson in response.
16. Even after causing damage to the hospital set, the production was only required to pay $250 per day for the shooting location.
17. Ken Kesey, the author and creator of the story, was deeply dissatisfied with the filmmakers’ alterations to his plot and characters in the adaptation of his book, leading him to vow never to watch the completed film. He initially wanted Gene Hackman for the role of Randle Patrick McMurphy, but the casting went to Jack Nicholson. Kesey objected to the film not being presented from Chief Bromden’s narrative and McMurphy being portrayed as a non-narrative antihero.
18. Kesey’s dissatisfaction led to file a lawsuit against the production, seeking 5% of the film’s gross profits and $800,000 in damages. Eventually, a financial settlement was reached. Years later, Kesey accidentally stumbled upon the movie while channel surfing, only to quickly change channels after realizing it was the same unwanted adaptation he had sworn off.
19. In the electroconvulsive therapy (ECT) scene in One Flew Over The Cuckoo’s Nest, McMurphy utters the phrase “a little dab will do ya” while the nurse applies conductor gel to the side of his head. This expression, not originally part of the script, serves as a reference to the advertising jingle of Brylcreem hair cream, a popular men’s hair care product in the 1960s and 1970s.
20. The film was made on a budget between $3 million and $4.4 million. It grossed over $160 million at the box office.
21. The film had three cinematographers during production due to various circumstances, including Haskell Wexler being replaced after 30 days of shooting.
