Talking to us from the 2010 Sundance Film Festival, directors Thet Sambath and Rob Lemkin discuss their documentary click 'Enemies of the People', a deeply moving and personal journey to uncover the truth behind the Killing Fields of Cambodia. Thet explains the importance of access to subjects in order to tell a story and describes how, over a period of 10 years, he managed to gain the trust of leaders and foot soldiers of the Khmer Rough, one of the 20th century's most brutal regimes.
