Maddox inspired Jolie’s new film

Angelina Jolie has credited her adopted son Maddox as her inspiration for her new film First They

Killed My Father, that’s based on her friend and former Cambodian refugee Loung Un’s life.

She told The Guardian, “I wanted to understand what my son’s (Maddox, who is also from Cambodia) birth parents may have gone through. And I wanted to know him better and I wanted to know this country better. He was the one who just called it and said he was ready and that he wanted to work on it, which he did. He read the script, helped with notes, and was in the production meetings,” according to Dailymail.co.uk.

Angelina made her first official appearance with Maddox and her other children in Siem Reap, Cambodia, on Saturday, since announcing her divorce from Brad Pitt last September.
