At the Auschwitz concentration camp in 1944, a band of Jewish prisoners would play an uplifting melody while new victims marched through the heavily guarded gates and smoke billowed from the crematoriums in the not-so-distant background. This type of ethical contradiction reoccurs repeatedly in Tim Blake Nelsons riveting The Grey Zone with the lines between right and wrong, responsibility and guilt often blurred. In this shocking true story the director of O Brother, Where Art Thou? focuses on one of the 12 Sonderkomandos used during World War II where captive Jews worked in the crematoriums, furnaces, and gas chambers herding unsuspecting kin to their death in order to receive a few extra weeks of survival, cigarettes and alcohol. The psychological ramifications of such severe denial to accept responsibility for the murders intensified, resulting in an uprising among the working inmates, which demolished the Sonderkomandos with smuggled explosives. This powerful exploration of humanity and morality exponentially increases with the bleak cinematography and inhibited portrayals of the real historical travesty that will leave a lasting impression on your heart and mind.
