hospital, Lisa tells Kathy that she had seen Jodie. George's behaviour towards Kathy and her children becomes abusive and the paranormal activity continues. One night, George hears Harry barking in the boathouse. Seemingly possessed, he grabs the axe and proceeds to murder the family dog. The children look for Harry the next day, with George denying he knows where he is, despite Billy's suspicions. Kathy asks the priest Father Callaway (Philip Baker Hall) to bless the house, as a protective measure to prevent any future paranormal incidents, but Father Callaway flees the house when he encounters such occurrences himself. Kathy discovers that the house once belonged to a cult preacher named Reverend Jeremiah Ketcham, whose evil actions towards Native Americans during his "mission" in 17th-century Amityville are said to be the cause of the haunting. Meanwhile, as George is walking through the basement of the house, encounters the apparitions of the various Native Americans who were tortured and killed there by Ketcham centuries ago. Entering a dimly-lit room, George encounters Ketcham himself (though he is not aware of who he is), and the ghostly figure of the evil missionary turns around, picks up a knife, and slits his throat in an act of recreating his suicide, covering George with blood, and causing him to become nearly completely possessed. Kathy becomes convinced that George's abusive behavior is owed to a spiritual possession. Following urgent advice from Father Callaway, Kathy tries to evacuate her children from the house and escort them to safety, but the possessed George attempts to kill her and the children; Kathy knocks him out to prevent him from doing so and transports him away from the residence via boat. Subsequently, George is released from the spirit's control and the family permanently leaves the house. A title card states that the family left within 28 days of arriving and never returned. Jodie is shown standing in the now-empty house and screaming in terror while the house rearranges itself back to its original state before the family's arrival. Subsequently, she is pulled beneath the floor by a pair of disembodied hands. Cast Production Although the film is set on Long Island, it was shot in Chicago, Antioch, Buffalo Grove, and Fox Lake, Illinois, and in Salem and Silver Lake, Wisconsin. The house used is a real 1800s home that was temporarily converted to add the famous quarter moon "eye" windows.
