Transcript for Angelina Jolie opens up about her new film 'First They Killed My Father'
Juju Chang used to be with me on this program and you're looking around going, it's different. Lots of people. A little different. You're here with a look back. Angelina Jolie has this new passion project. She is something else. She really is and this is very much an ode to Cambodia, a country she loves and first visited for Lara croft tomb raider and stumbled on this story. 17 years later it is a place where she is a citizen, where she first became a mom, a place whose dark history she has now turned into a movie. One of Hollywood's most famous faces stepping behind the camera once again, Angelina Jolie directing her latest film "First they killed my father". The tag line in the movie is a daughter of Cambodia remembers so that others won't forget. Cambodia has a beautiful ancient thousands of year-old, you know, glorious past but also a past that is -- has war and genocide and so I felt that it was really important, this country I love so much to discuss. Reporter: Jolie teaming up with rhythmy pan to make the film based on the memoir of Jolie's friend. The movie a heart wrenching and unfliping account of the Cambodian genocide. Why is it helpful to see this through the eyes of a child? Through your eyes? I think people sometimes when they talk about genocide and crimes against humanity and war, they forget the most vulnerable victims are the children. Am I a prisoner. Reporter: You did "Unbroken." What have they taught you if anything about the human cost of war. When you direct a film you spend years understanding, analyzing and I want to know how people get to a place where they do such harm to each other. This is not 40 years ago. This is today. We have 45 million people displaced today. We have so many ongoing wars. What is worse is then we could say if we knew, we know. We know so much now. If anything we see people more divided and see people encouraged to board up and wall up and divide more. So it is something we must be very conscious of today. Reporter: The 42-year-old actress and humanitarian adopted her oldest son Maddux from Cambodia and the 16-year-old serving as an executive producer. I'm proud to be Cambodian understanding who he is and that's the most important thing that came out of this experience. Come to see us to end up chichi come to be with us. You're getting emotional. I met Maddux -- I felt connected to the country. I felt that I should be a family from that country and I knew when I saw his eye, I knew I Mitt him. Reporter: It's been a quite a year for Jolie separating from Brad Pitt as well as struggling with hypertension and bell's palsy. People are concerned about your health issues. How are you doing? How was the recovery? I'm fine right now. You are? Yeah, I'm fine right now. My children are healthy. I'm healthy and thank you. Reporter: Jolie refusing to discuss her personal life choosing to focus on the film. This is a country that deserves to -- for people to know about its people and in a way that they deserve to be seen. And Jolie hit the red carpet with her child stars and all six of her kids in New York City for the premiere and last night she also had a busy day meeting with the U.N. Secretary-general because of her ongoing work with refugees of modern wars, as well. Always so passionate.
