The actress revealed earlier this year she suffered from Bell's Palsy in 2016, telling Vanity Fair: "Sometimes women in families put themselves last, until it manifests itself in their own health.”
Jolie's six children remained with her in Cambodia while she made the new film, with her son Maddox, who was born in the country, helping with its production.
"I really wanted Maddox to learn about Cambodian history, so I felt that this movie was a journey that we could take," she says. "And he went really deeply into the research and into the edit. And having somebody younger there to say, 'you are losing my attention,' or 'that is too complicated,' was really helpful."
"The children have been amazing," she adds. "It's been so moving to see how much they have helped each other and how much they have helped me."
