The Exorcist (1973)

In William Friedkin's blockbuster horror film about demonic possession, there were many scary scenes of possessed twelve year-old Regan MacNeil's (Linda Blair) monstrous appearance with a vicious demon inside of her:

• the scene at ancient temple ruins in Northern Iraq when elderly Jesuit priest Father Merrin (Max von Sydow) confronted the demonic statue of Pazuzu
• the film's intense special effects and violent horrors of devil possession, and twelve year-old Regan MacNeill's monstrous appearance
• her public urination on the rug during a Georgetown party
• Regan's back-handed slapping of a doctor across the face and knocking him into a door and onto the floor, as her physically-repulsive voice warned: "Keep away! The sow is mine!" She pulled up the front of her nightgown, masturbated by rubbing herself, and in a deep, strange voice, beckoned: "F--k me! F--k me!"
• the terrifying visit to a hospital where Regan was subjected to a controversial and lengthy excruciatingly-torturous medical examination sequence (and blood-letting) with markedly sexual overtones
• the notorious self-abusive crucifix-masturbation (or stabbing) scene of Regan's crotch with a bloody crucifix, as she bellowed obscenities in the Devil's voice: "Let Jesus f--k you, let Jesus f--k you! Let him f--k you!" - she spun her head backwards 180 degrees, threatening in a deep malevolent voice as she imitated the British accent of a dead family friend to taunt Chris about his murder: "Do you know what she did? Your c--ting daughter?"

Controversial Self-Abuse with Crucifix Sequence

• the scene of pea-soup spewing, after Father Damien Karras (Jason Miller) entered the bedroom and saw the girl strapped to a padded four-poster bed. Her face was cut, her hair matted, her eyes wild-looking, and she had a plastic tube taped to one nostril. The grotesque girl spoke with a disgusting, low-pitched growl coming straight from hell. As he approached closer, in the grossest scene of the film, Regan lurched forward on the bed and spewed bilious, pea-green soup vomit from her mouth in a single projectile stream directly into his face. The thick green slime stuck to his face and clothing. Bits of vomit and bile acid also dribbled down onto Regan's nightgown

Vomit-Spewing

• the silhouetted image of the arrival of the elderly Jesuit priest Father Merrin on a dark and foggy night under a lamp-post outside the MacNeill's Georgetown house
• her demonic tortured and vulgar voice (supplied by veteran character actress Mercedes McCambridge) that screamed foul obscenities and diabolical sounds that emanated from her mouth - growling dogs, squealing pigs, rasping groans, and foul language; raised welts that bubbled up across her abdomen read: "help me."
• one of the other most objectionable and blasphemous scenes was the sight on the Georgetown University campus of a white marble statue of the Virgin Mary. It had been desecrated with red paint and other materials, and taken on the appearance of a harlot. The defiled statue had long red-tipped breasts, red color on both hands, and an elongated, erect yet sagging penis-shaped clay protuberance also daubed in red.
• the bedside exorcism ceremony, when Regan shouted insults at Father Karras: ("Your mother sucks c--ks in hell, Karras"), followed by her 360-degree spinning head as she sat up in bed
• the demise of Father Damien Karras when he dared the devil to enter his body: ("Take me. Come into me. God damn you. Take me. Take me") - and he threw himself through Regan's bedroom window to his death in the street below; he gave his own life to save Regan's spirit and life, with the promise of being reborn; from the bedroom window, Lt. Kinderman (Lee J. Cobb) viewed Karras' bloodied body at the foot of the Prospect Street steps

• Father Dyer (William O'Malley) broke through and grabbed Karras' dying hand, beseeching him: "Do you want to make a confession? Are you sorry for having offended God and for all the sins of your past life?" Signaling his assent, Karras unclenched and gripped Dyer's hand; Dyer absolved him of his sins during the administration of last rites
