10 Disturbing Movies You'll Struggle To Finish

Far more serious than any fictional crimes committed to celluloid by the Japanese film industry are the crimes of the Japanese military during their occupation of China before and during the Second World War. In addition to the brutal rape of Nanking, Japanese scientists took a leaf out of the Nazi's playbook and performed murderous experiments on hapless Chinese prisoners.

This is the subject of Men Behind The Sun, a Chinese production directed by T. F. Mou designed to highlight the Japanese atrocities at Unit 731, a biological warfare unit which carried out these medical experiments. The film depicts these horrors without flinching: prisoners are infected with plague; a woman has her arms frozen and shattered; women are raped and tortured; many more are murdered.

Men Behind The Sun has a number of scenes which are contenders for the point where you turn the film off, including the notorious scene in which a cat appears to be eaten alive by rabid rats and a scene of the autopsy of a young boy in which the filmmakers are alleged to have used real footage of an actual autopsy. It goes without saying this is not for the faint of heart.
