<P> Spielberg wanted Donovan's death shown in one shot, so it would not look like an actor having makeup applied between takes . Inflatable pads were applied to Julian Glover's forehead and cheeks that made his eyes seem to recede during the character's initial decomposition, as well as a mechanical wig that grew his hair . The shot of Donovan's death was created over three months by morphing together three puppets of Donovan in separate stages of decay, a technique ILM mastered on Willow (1988). A fourth puppet was used for the decaying clothes, because the puppet's torso mechanics had been exposed . Complications arose because Alison Doody's double had not been filmed for the scene's latter two elements, so the background and hair from the first shot had to be used throughout, with the other faces mapped over it . Donovan's skeleton was hung on wires like a marionette; it required several takes to film it crashing against the wall because not all the pieces released upon impact . </P> <P> Ben Burtt designed the sound effects . He recorded chickens for the sounds of the rats, and digitally manipulated the noise made by a Styrofoam cup for the castle fire . He rode in a biplane to record the sounds for the dogfight sequence, and visited the demolition of a wind turbine for the plane crashes . Burtt wanted an echoing gunshot for Donovan wounding Henry, so he fired a . 357 Magnum in Skywalker Ranch's underground car park, just as Lucas drove in . A rubber balloon was used for the earthquake tremors at the temple . The film was released in selected theaters in the 70 mm Full - Field Sound format, which allowed sounds to not only move from side to side, but also from the theater's front to its rear . </P> <P> Matte paintings of the Austrian castle and German airport were based on real buildings; the Austrian castle was a small West German castle that was made to look larger . Rain was created by filming granulated Borax soap against black at high speed . It was only lightly double exposed into the shots so it would not resemble snow . The lightning was animated . The airport used was at San Francisco's Treasure Island, which already had appropriate art deco architecture . ILM added a control tower, Nazi banners, vintage automobiles and a sign stating "Berlin Flughafen". The establishing shot of the Hatayan city at dusk was created by filming silhouetted cutouts that were backlit and obscured by smoke . Matte paintings were used for the sky and to give the appearance of fill light in the shadows and rim light on the edges of the buildings . </P> <P> A son's relationship with his estranged father is a common theme in Spielberg's films, including E.T. the Extra-Terrestrial and Hook . </P>
