The movie premiered at 2017 Telluride Film Festival on Saturday, September 2 in Colorado. Maddox, 16, Pax, 13, Zahara, 12, Shiloh, 11, and 9-year-old twins Knox and Vivienne supported their mother at the event. After hitting film festival circuit, the film will debut in theaters and start streaming on Netflix on September 15.

The movie takes place in Cambodia from where Maddox was adopted by Angie. It's adapted from Loung Ung's 2000 memoir of the Khmer Rouge genocide. Maddox was credited as an executive producer while Pax whom the actress adopted from Vietnam worked as the film's still photographer.

"Mad has known of Loung's story his whole life, and I told him, 'One day, son, you will be ready and you will tell me it's time to go deeply into your country. But I need your help and you have to work and you have to be there every day and you can't say no and that you are tired,' " the mother of six told The Telegraph. "And one day he said, 'I am ready.' "
