Unhinged

Unhinged is a 1982 American exploitation slasher film directed by Don Gronquist, written by Gronquist and Reagan Ramsey. The film follows three young women who are taken in by a mysterious family at their rural mansion after getting into a car accident. It is perhaps most notable for being among the United Kingdom's 72 "video nasties," which led to an expanded role for the British Board of Film Classification. The movie was filmed in Portland, Oregon, using interiors and exteriors of Pittock Mansion.
