Angelina Jolie brought her six children to the premiere of First They Killed My Father at the Toronto International Film Festival. Jolie directed the film while her son Maddox, 16, served as executive producer and Pax, 13, served as an onset photographer.

Joining Jolie’s family were Loung Ung, who wrote the memoir First They Killed My Father, as well as the film’s stars Kimhak Mun and Sareum Srey Moch.

The film has been a passion project for Jolie who was motivated to bring the story to life by Maddox, her son who was born in Cambodia.

The film opens in theaters on September 15th and will be available to stream on Netflix the same day.
