to be spliced with footage from the studio. Another crew filmed day and night footage on Highway 99 between Gorman and Fresno, California for projection when Marion drives from Phoenix. Footage of her driving into Bakersfield to trade her car is also shown. They also provided the location shots for the scene in which she is discovered sleeping in her car by the highway patrolman. In one street scene shot in downtown Phoenix, Christmas decorations were discovered to be visible; rather than re-shoot the footage, Hitchcock chose to add a graphic to the opening scene marking the date as "Friday, December the Eleventh". Green also took photos of a prepared list of 140 locations for later reconstruction in the studio. These included many real estate offices and homes such as those belonging to Marion and her sister. He also found a girl who looked just like he imagined Marion and photographed her whole wardrobe, which would enable Hitchcock to demand realistic looks from Helen Colvig, the wardrobe supervisor. The look of the Bates house was modeled on Edward Hopper's painting House by the Railroad, a fanciful portrait of the Second Empire Victorian home at 18 Conger Avenue in Haverstraw, New York. Lead actors Perkins and Leigh were given freedom to interpret their roles and improvise as long as it did not involve moving the camera. An example of Perkins's improvisation is Norman's habit of eating candy corn. Throughout filming, Hitchcock created and hid various versions of the "Mother corpse" prop in Leigh's dressing room closet. Leigh took the joke well, and she wondered whether it was done to keep her in suspense or to judge which corpse would be scarier for the audience. Hitchcock was forced uncharacteristically to do retakes for some scenes. The final shot in the shower scene, which starts with an extreme close-up on Marion's eye and zooms in and out, proved difficult for Leigh because the water splashing in her eyes made her want to blink, and the cameraman had trouble as well because he had to manually focus while moving the camera. Retakes were required for the opening scene because Hitchcock felt that Leigh and Gavin were not passionate enough. Leigh had trouble saying "Not inordinately" for the real estate office scene, requiring additional retakes. Lastly, the scene in which "Mother" is discovered required complicated coordination of the chair turning around, Vera Miles (as Lila
