Matte paintings by Michael Pangrazio were used to create more elaborate backgrounds: these included the establishing shot of Marion's Nepalese bar and the warehouse where the Ark is later stored. Spielberg disliked the painting of the China Clipper plane as he did not think it looked real against the water they had filmed. Jones' attire—a leather jacket and khaki pants—was based on Humphrey Bogart's in "The Treasure of the Sierra Madre" (1948) and Charlton Heston in "Secret of the Incas" (1954). Costume designer Deborah Nadoolman Landis dumped boxes of hats on the floor for Ford to try on. After picking the right style, Nadoolman Landis purchased an Australian model she aged with Fuller's earth and mineral oil, and then scrunched beneath a bed. The hat allowed them to create a recognizable image even in silhouette. Designer Ralph McQuarrie was responsible for the Ark decorations.
