This video is called The Exorcist 1973 trailer.
In the 1973 horror movie The Exorcist, the villain is a teenage girl (or, rather, a demon possessing her); and the good guy is an exorcist priest.
However, in 2015 real life, things are a bit different.
From daily The Guardian in Britain:
Priest questioned over 13 exorcisms allegedly performed on anorexic teen
Court to investigate whether practice crossed line into abuse after girl’s parents sent her for exorcisms thinking she was possessed

A priest has been summoned to court to answer questions about more than a dozen exorcisms he allegedly carried out on an teenage girl with anorexia.
The investigation began after the girl and members of her extended family complained to the Spanish authorities in August that she had been put through at least 13 exorcisms.
The girl, from the northern city of Burgos, told police that she began having problems with anorexia and anxiety when she was 16, which her parents saw as a “sign of her possession by the devil”.
She was undergoing psychiatric treatments at the time, in May 2012, but her parents, convinced that exorcisms would help, took her to a priest from Valladolid, who carried out several of them on her over a three-month period.
The girl told authorities she was forced to lie on the ground and tied up, with crosses placed over her head. Images of saints were put on her body during the ritual, which often lasted between one and two hours.
In her initial filings, the judge said that the practice of exorcisms on the girl may have crossed the line into “domestic violence, causing injury and abuse”, according to Diario de Burgos, a Spanish newspaper.
The archdiocese of Burgos said in a statement: “After the girl was admitted various times to hospitals in Burgos and Valladolid, her parents, distraught on seeing that she wasn’t recovering, brought her to the exorcist.” It added that the girl’s parents alone made the decision to treat her through exorcisms.
Defending the rituals, the archdiocese said: “Exorcisms are a religious practice that has been maintained as part of the church’s tradition, and is a right available to all of the faithful.”
The exorcist at the centre of the case, it added, had been legitimately appointed by a bishop.
The priest, who has not been formally charged, is expected to appear in court in the coming weeks.
Spain has an estimated 15 priests authorised to carry out exorcisms, eight of whom were added in 2013, by the then Archbishop of Madrid, Antonio María Rouco Varela, reportedly to meet increasing demand for the practice.
If not for horror films like The Exorcist, there would probably be less demand for exorcism.
