The film drew mixed reviews and was a success at the box office. However, not much of the events recounted in the book actually remain in the film, as most have been changed and re-imagined by the scriptwriters/producers of the script/film. The film followed Sarchie (Eric Bana) into the paranormal investigations he immersed himself in, all the while taking care of his family and working the midnight-to-8:00 A.M. On July 2, 2014, Screen Gems/ Sony Pictures released a full-length motion picture, Deliver Us from Evil, inspired by Sarchie's accounts. Schooled in the rituals of exorcism, and an eyewitness to the reality of demonic possession, Ralph Sarchie has documented a riveting chronicle of the inexplicable that gives a new shape to the shadows in the dark. Now he discloses for the first time his investigation into incredible true crimes an inhuman evil that were never explained, solved, or understood except by Sarchie and his partner. But it is his other job that he calls 'the Work': investigating cases of demonic possession and assisting in the exorcisms of humanity's most ancient-and most dangerous-foes. 'A seventeen-year NYPD veteran, Ralph Sarchie works out of the 46th Precinct in New York's south Bronx. Martin's Press published Sarchie's book, Beware the Night (also titled Deliver Us from Evil), co-written by Lisa Collier Cool, about his experience as a NYPD cop and demonologist. When interviewed with TheBlaze, he stated that he has 'never accepted a penny for his assistance' and has to fund travelling expenses himself when he takes on cases. Sarchie states that demonic possession can be identified by signs 'including unnatural strength, speaking in different languages, having knowledge of events that one would have no way of knowing, a woman speaking in a man’s voice and a person making animal sounds.' He states that he prays everyday and among these prayers are the Dominican rosary. His career as a Catholic Christian demonologist has included regularly meeting with and accompanying Ed and Lorraine Warren on their cases. Ralph Sarchie, along with his partner Mark Stabinski, carry with them wooden Christian crosses and holy water when called to tackle 'demonic infestation around the city.' He assists in Christian exorcisms. Although he was raised in a Roman Catholic Christian family, Sarchie's faith waned 'but it's now fully restored.' As such, Sarchie describes himself as a 'committed Christian' he posesses a relic of the True Cross. Sarchie served eighteen years as a NYPD sergeant in the South Bronx precinct.
