Unhinged (1982)

Unhinged is a 1982  American  exploitation   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. [2]  The movie was filmed in  Portland, Oregon, using interiors and exteriors of  Pittock Mansion. A remake of the film was made in England and released in 2017.
