<P> Kong's torso was streamlined to eliminate the comical appearance of the real world gorilla's prominent belly and buttocks . His lips, eyebrows, and nose were fashioned of rubber, his eyes of glass, and his facial expressions controlled by thin, bendable wires threaded through holes drilled in his aluminum skull . During filming, Kong's rubber skin dried out quickly under studio lights, making it necessary to replace it often and completely rebuild his facial features . </P> <P> A huge bust of Kong's head, neck, and upper chest was made of wood, cloth, rubber, and bearskin by Delgado, E.B. Gibson, and Fred Reefe . Inside the structure, metal levers, hinges, and an air compressor were operated by three men to control the mouth and facial expressions . Its fangs were 10 inches in length and its eyeballs 12 inches in diameter . The bust was moved from set to set on a flatcar . Its scale matched none of the models and, if fully realized, Kong would have stood thirty to forty feet tall . </P> <P> Two versions of Kong's right hand and arm were constructed of steel, sponge rubber, rubber, and bearskin . The first hand was non articulated, mounted on a crane, and operated by grips for the scene in which Kong grabs at Driscoll in the cave . The other hand and arm had articulated fingers, was mounted on a lever to elevate it, and was used in the several scenes in which Kong grasps Ann . A non articulated leg was created of materials similar to the hands, mounted on a crane, and used to stomp on Kong's victims . </P> <P> The dinosaurs were made by Delgado in the same fashion as Kong and based on Charles R. Knight's murals in the American Museum of Natural History in New York City . All the armatures were manufactured in the RKO machine shop . Materials used were cotton, foam rubber, latex sheeting, and liquid latex . Football bladders were placed inside some models to simulate breathing . A scale of one - inch - equals - one - foot was employed and models ranged from 18 inches to 3 feet in length . Several of the models were originally built for Creation and sometimes two or three models were built of individual species . Prolonged exposure to studio lights wreaked havoc with the latex skin so John Cerasoli carved wooden duplicates of each model to be used as stand - ins for test shoots and lineups . He carved wooden models of Ann, Driscoll, and other human characters . Models of the Venture, railway cars, and war planes were built . </P>
