The exterior of the Hillard house, which served as a main setting for the film, is a real house located at 2640 Steiner Street in the Pacific Heights neighborhood of San Francisco. The interiors of the house were filmed in a former candy warehouse in the Richmond District, and KTVU’s television studios in Oakland were also used for some of the filming. The film’s producers chose the Hillard house for its beautiful Victorian architecture and its location, which offered stunning views of the city.
