Angelina Jolie's new film "First They Killed My Father" is based on author and human rights activist Loung Ung's account of her survival as a child under the 1975-79 communist Khmer Rouge regime. Jolie said Saturday that she hopes the film about Cambodia will help educate the world about the brutality of the 1970s regime and shed a light on the plight of young people in war zones today. Jolie has had an affinity for Cambodia since she began goodwill work for the U.N.
