The Devil Inside is a 2012 American found footage supernatural horror film directed by William Brent Bell and written by Bell and Matthew Peterman. It is a documentary-style film about a woman who becomes involved in a series of exorcisms during her quest to determine what happened to her mother, a woman who murdered three people as a result of being possessed by a demon. Produced by Peterman and Morris Paulson, the film stars Fernanda Andrade, Simon Quarterman, Evan Helmuth, and Suzan Crowley, and was released theatrically on January 6. Despite receiving poor reviews from critics and audiences, it was a commercial success and grossed over $101 million. The film topped the US box office on its opening weekend, yet dropped drastically in the second week, before disappearing completely from the box office top ten. Plot On October 30, 1989, Maria Rossi committed a triple murder during an exorcism performed on her. The Catholic Church became involved, and she has since been in a Catholic psychiatric hospital in Rome. A news story and police investigation show the three members of the clergy whom she murdered. Her daughter, Isabella, learned of the murders from her father, who died three days after telling her. Twenty years later, Isabella is in the process of filming a documentary with filmmaker Michael Schaefer about exorcisms and, to find out more about her mother, she visits a school in Rome. She meets two priests, Ben Rawlings and David Keane, before going to see her mother Maria in the asylum. She finds that her mother speaks in different accents and has paintings all over the walls. Maria then soils herself while screaming in an unidentified language. She has inverted crosses carved into her arms and her bottom lip and tells Isabella that killing a child is against God's will. Isabella tells the priests that she had an abortion years ago and her mother had no way of knowing that—another sign that showed possible possession. David and Ben take her with them on an unsanctioned exorcism performed on Rosalita, a young woman. They bring medical equipment to determine if it is possession or mental illness. Rosalita calls Isabella by her name, despite not knowing her, and attacks the crew after spouting out obscene remarks in different languages and accents. Eventually, they get her under control. As the crew discusses performing an exorcism and analysis on Maria, David worries
