The hospital psychiatric ward can be seen as a metaphor for one individual's fight against a power-hungry, cruel oppressor. McMurphy shows the astounding difference one courageous person can make in many lives. He lifts the spirits of the weak, takes steps toward the toppling of a tyrant, and has a lasting effect on those who have been subjected to inhuman treatment.
Patients intermittently get upset, lose control, and have to be forcibly restrained by staff, sometimes very roughly. There are some violent outbursts, an occasional fight, including one in which a patient attempts to strangle his adversary. A sadistic nurse causes great harm to several of the patients. (Spoiler alert) There are two deaths in the film: one is a bloody victim of suicide, the other dies at the hands of a patient.
No overt sexual activity, however, there is brief partial nudity. There are several sly sexual jokes, as well numerous humorous references to masturbation. One patient discusses his sexual problems. On two occasions female "party girls" join the patients and ultimately disappear behind closed doors.
Frequent swearing and obscenities including multiple uses of "Goddamn," "son-of-a-bitch," "hell," "s--t", "c--t," "crap," bulls--t," "a--hole," many forms of forms of "f--k" and more. There are several ethnic and homophobic slurs, usually delivered with a sense of humor, such as: ""Mormon a--hole," "dumb Indian," and "queer."
Drinking, Drugs & Smoking
Patients smuggle liquor into the ward and drink heavily during a wild and unorthodox party sequence. Characters smoke cigarettes continuously.
