This study investigated the diagnostic decisions regarding the case of a Bedouin psychiatric patient, called “M”, who underwent sudden and severe behavioral changes. He felt angrily towards his mother’s disrespect for his wife, eventually instigating several arguments, and nearly physically attacked her.

He was referred to the nearest biomedical hospital, where he was diagnosed as a paranoid schizophrenic with auditory and visual hallucinations that were themed around demonic images. The psychiatrist also gave him anti-psychotics in order to alleviate the hallucinations. Though the drugs calmed him, they did not eliminate these intrusive images. M failed to improve until he received guidance from a social worker, who arranged treatment with a traditional healer upon consideration of his Muslim background. (Because they highly regard the Mother figure, any wrongdoing towards her is considered sinful. Thus, M believed that God inflicted punishment by imbuing him with evil spirits.)

The healer, or Dervish, functions as a Bedouin version of an exorcist, working to treat mental and physical illness through the use of ritual and prayer. He diagnosed M as being possessed by demons, and went on to perform Tazeem, which is a dialogue with spirits—much like Western exorcism. The Dervish overpowered the evil spirits and managed to quickly relieve M of both his hallucinations and pent-up anger.

He continued seeing both biomedical and traditional practitioners until he felt fully restored. The psychiatrist admitted his initial diagnosis was incorrect, since the medications were not appropriate for M’s condition as he should have been classified as neurotic. Understanding his cultural framework, which insists on an external locus of control, was crucial for offering him effective treatment. Thus, the modern, scientific system would have been futile without the integration of traditional, religious-inspired practices. The authors posit that both realms should be seen on the same level, as complementary structures enriching one another.

In terms of the film, The Exorcist presented the ritual as outrageous and dramatic. However, this actually promoted the curiosity of many viewers, compelling them to explore the possibility of exorcism as a real phenomena with tangible benefits. People began to entertain ideas relating to practices of the occult, which involve superstition and supernatural powers; many took an interest in studying foreign cultures and understanding their belief systems for healing. As addressed in this article, it turned out that the synthesis of both science and religion proved to give the best outcome.

Hence, the film was influential in shaping America’s modern day religious scene. Many fans started to explore what they initially feared, opening up their minds to a new world in which otherwise ‘strange’ and seemingly ‘uncultivated’ practices were discovered to be actually useful towards mental health. In essence, people began to realize that biomedicine, alone, does not always provide the best answers.

Based on his best-selling novel, The Exorcist was written and produced by William Peter Blatty, who worked alongside Hollywood director William Friedkin. The film was influenced by an actual exorcism case involving the supposed demonic possession of a fourteen-year-old boy in a suburb of Washington D.C. A student at the Jesuit Georgetown University at the time, the young Blatty felt that the boy's eventual healing was proof of the devil's existence, and thus the power of God, heaven, and faith.

The film recounts the story of Regan, a pre-pubescent girl living with her single mother, Chris MacNeil, in a posh Georgetown suburb. All is going well until Chris hears strange sounds in the attic, which is followed by a series of peculiar behaviors elicited by Regan. She becomes unruly, urinates in front of guests, and uses gratuitous profanity among other things.

Her mother is shocked and desperate, so quickly consults a team of doctors for her care. Regan undergoes several intensely painful medical procedures, but nothing seems to give definitive physical results. After the death of a family friend and her continually dangerous behavior, the doctors 'give up' and resort to religious means. They suggest the ritual of an exorcism in helping Regan get back to her usual self.

Chris approaches Father Karras to perform the exorcism. After much hesitation and doubt on his part, he eventually agrees to do so under the instruction of the experienced Father Merrin. What ensues is a fight between good and evil, where both sides pay a price for the liberation of little Regan.

Overall, The Exorcist proved to be a breakthrough in contemporary horror film, setting the stage for future successes in this genre. On the surface, the film was popular because of its cinematic craftsmanship, successfully achieving basic elements of a horror film and portraying supernatural events as highly realistic for its time. Additionally, on a deeper level, its exploration of controversial issues tapped into the true fears and concerns of crowds at large. Both of these cinematic and thematic aspects contributed to the film's wide appeal.

This annotated bibliography provides a brief list of sources that investigate these topics.

(It should be noted that there are certainly several controversial themes highlighted in the film. Such include, but are not limited to: female and child victimization, uncontrollable youth, violation and disfigurement of the body, offensive language, sexual vulgarity, desecration of the Catholic Church, breakdown of the family, destruction of the home, etc. Since this project only entails ten items, I have chosen to focus on one overarching issue that the film forces us to contemplate--the roles of religion and science/modern day medicine in the healing process. I present four sources that offer differing views on this; the other six describe cinematic techniques, of which two assess their credibility based on audience reaction.)
