the adults to work in the Gamera universe". Yuasa made Eiichi point out Gyaos' nocturnal nature, feeling that it was a detail only a child would notice. Yuasa felt one of the film's messages was to show the purity of children, stating, "I think the main point of the whole film is that Eiichi and Gamera had some sort of bond or one mind. I thought that was better than some needless exposition." The car split scene was added after Takahashi saw the Toyota Corolla deluxe at a motor show, as a result, the vehicle was not produced for the film. Special effects The special effects were directed by Noriaki Yuasa. Gyaos was designed by art director Akira Inoue. The Gamera suit was recycled from Gamera vs. Barugon, however, the eyes were modified to look more friendly. The upper-half portion of the suit from Gamera, the Giant Monster was recycled for fire-breathing scenes. The Gamera shell that Eiichi rides was a full scale prop built at 20 meters square. The monster footage was filmed on an indoor soundstage set. Yuasa recalled spending time, energy, and money on the shot of the miniature volcano exploding, however, he later felt the result was not worth it. Yuasa disliked the oatmeal formula used to simulate flowing lava in other films and instead backlit translucent molds and had them pulled by hidden cables. Yuasa felt that nighttime matching shots were more easier to achieve than daytime opticals due to film elements not requiring precision. The Gyaos cave was a set constructed at Daiei. For the scene with Okabe being lifted by Gyaos, the camera was tilted at a 90 degree angle while the background shifted horizontally. The full scale Gyaos claw was operated by three people that required them to pull on a cable attached to it. Historian Stuart Galbraith IV deduced that the giant Gyaos claw was recycled for Gyaos' severed toes. Gamera's blood was pumped manually by the crew, which Yuasa found difficult to match the animation to Gyaos' beam. For the shot of Eiichi climbing Gamera's shell, Yuasa filmed a stunt double climbing a ladder that was later layered into the shell. The Highland Park miniature was based on Fuji-Q Highland. The Hotel Hi-land miniature was inspired by the Hotel New Otani Tokyo, which upset the then-hotel president and told Daiei president Masaichi Nagata, "we're barely open yet Gamera has already
