Just watched a new experimental film titled, WHAT WE SHARED. Highly recommend it, as it speaks about the displacement of people and horrific experiments led by Stalin's insane Soviet communist regime. Stalin even had a monkey academy meant to cross breed humans with chimps in order to create a new kind of warrior for Soviet war and rule.
