In this photo taken Thursday, Feb. 20, 2014, a metal cot is displayed in a room used as a torture chamber at the Tuol Sleng Genocide Museum, formerly the most notorious Khmer Rouge prison, in Phnom Penh, Cambodia. The office of Cambodia's most celebrated filmmaker is filled with books on the Khmer Rouge - on his desk, on the walls, in the filing cabinets and in every corner of Rithy Panh's dimly lit office are memories of his country's national tragedy. In his latest movie, the 51-year-old filmmaker focuses for the first time on his personal story of loss and tormented survival. "The Missing Picture" won an award at last year's Cannes Film Festival and is up for Best Foreign Language Film at the Oscars this weekend, marking the first time a Cambodian film has been nominated for an Academy Award.
