Catherine Deneuve in Repulsion (1965, dir. Roman Polanski)

“My aim was to show Carole’s hallucinations through the eye of the camera, augmenting their impact by using wide-angle lenses of progressively increasing scope. But in itself, that wasn’t sufficient for my purpose. I also wanted to alter the actual dimensions of the apartment — to expand the rooms and passages and push back the walls so that audiences could experience the full effect of Carole’s distorted vision.  

 Accordingly we designed the walls of the set so they could be moved outward and elongated by the insertion of extra panels. When ‘stretched’ in this way, for example, the narrow passage leading to the bathroom assumed nightmarish proportions.”

-Polanski, quoted in Roman (1984)
