Man Behind The Sun 1988
>Story of a Japanese terror camp in the end of WW2, where the Japanese are using the Chinese as guinea pigs in terrible experiments to develop deadly bacterial-plagues
>There was no special effects industry in China when this film was made so many of the special effects in the film were done with real cadavers which director Tun-Fei Mou was able to obtain through connections of his. The frostbite experiment victim's arms were real corpse arms and the child's body was a real cadaver. Mou waited for a whole month to find a body the same size as the child playing the role. He was almost ready to give up when the local police called him telling him that a child had been killed in an accident. He got permission from the parents and filmed the child's autopsy, dressing the coroners up like WWII-era Japanese doctors. The close ups of the child's organs being removed were done by dissecting a pig.
