Angelina Jolie's maternal instincts are interfering with her directing.The 40-year-old actress/director is currently shooting "First They Killed My Father," based on activist Loung Ung's memoir memoir of the same name, in Cambodia. One of the movie's scenes, Jolie told People, requires "250 children" who "have to cry and scream" as they "go through a labor camp." "My instinct is to want to cut and hug everyone," Jolie said.Jolie and husband Brad Pitt's 14-year-old son Maddox, adopted from Cambodia in 2001, is serving as PA on the fim. Jolie, speaking with the Associated Press in July, said "as Maddox and I prepare the film we will be side by side learning about his country ... He is my son but he is also a son of Cambodia. This is the time for our family to understand all that that means to him and to us. My desire to tell this story in the most truthful and accurate way possible will be my tribute to the strength and dignity of all Cambodian people." She added, "Maddox will be on set every day after school and involved behind the scenes." "First They Killed My Father" tells the story of Ung's brutal childhood under Cambodia's Khmer Rouge regime, responsible for the murder of millions of civilians. Jolie said the goal of the film "is not to revisit the horrors of the war but to bring to the screen characters that people around the world will empathize with, and to help other people to learn about Cambodia." She explained, "What is special about this particular story is that it is told from the perspective of a 5-year-old child, and is based on a child's emotional experience of war. It sheds light not only on the experience of children during the genocide in Cambodia but of all children who endure war." Jolie and Pitt star in the new marital drama "By the Sea," written and directed by Jolie. The film bombed at the box office and has been slammed by critics.
