Exorcism
In Catholic Christianity, exorcisms are performed in the name of Jesus Christ. A distinction is made between a formal exorcism, which can only be conducted by a priest during a baptism or with the permission of a bishop, and "prayers of deliverance" which can be said by anyone.
The Catholic rite for a formal exorcism, called a "Major Exorcism", is given in Section 11 of the Rituale Romanum. The Ritual lists guidelines for conducting an exorcism, and for determining when a formal exorcism is required. Priests are instructed to carefully determine that the nature of the affliction is not actually a psychological or physical illness before proceeding.
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.
