Exorcism
In Catholic practice the person performing the exorcism, known as an exorcist, is an ordained priest. The exorcist recites prayers according to the rubrics of the rite, and may make use of religious materials such as icons and sacramentals. The exorcist invokes God—specifically the Name of Jesus—as well as members of the Church Triumphant and the Archangel Michael to intervene with the exorcism. According to Catholic understanding, several weekly exorcisms over many years are sometimes required to expel a deeply entrenched demon.
Exorcismus
Secluded, home-schooled teenager Emma's uncontrolled behaviour causes her to believe she is possessed by the Devil. When terrible things start to happen to her friends and family, her parents grudgingly call in the help of her uncle, who is a priest, to drive out the evil spirits.In November 2008 Luis de la Madrid was set to direct the exorcism film, but on 22 September 2009 he was replaced by Manuel Carballo. The Spanish director David Muñoz wrote the script, and shooting began on 5 October 2009 in the Studios of Filmax.
