 In his DVD commentary, Clive Barker (I) (qv) explained that  filming the movie in an actual house forced him to be creative in  his cinematography. There was often only room for a single camera  and this explains why many of the shots are from only one angle. In  particular, vertical movement was often the only movement available  to the camera operators, which explains many of the overhead and  zoom shots. Only one room in the house, the attic, was shot on a  soundstage, but only the FX shots used this attic set.
