Since his early days as a correspondent covering the wars in Southeast Asia in the 1960s and 1970s, documentary filmmaker and journalist John Pilger has been an ardent critic of Western foreign policy. Following in the footsteps of Martha Gellhorn, Pilger set out to cover the Vietnam War from the perspective of those most affected by it – the Vietnamese people and US draftees. In 1979, he filmed Year Zero: the Silent Death of Cambodia, which depicted the humanitarian catastrophe following the ousting of the Khmer Rouge from Phnom Penh. He would go on to make three more films about Cambodia and become an outspoken critic of the United States’ intervention in the country and the West’s support of Pol Pot.
