She is a peerless glamazon as well as the women’s health advocate who told the world about her preventative double mastectomy. She has a meticulously managed public profile yet professes not to care what others think. She remains near the pinnacle of celebrity’s cruel pyramid, even though her recent movies only made money when she was camouflaged (“Maleficent,” “Kung Fu Panda”). She is obsessed over — if, in the United States at least, not exactly beloved — and fixed in the cultural firmament as America’s vixen despite having a half-dozen strong brood.
And even though the public appetite for salacious details of her personal life has long eclipsed interest in the films she has directed, Ms. Jolie doggedly brings tough, obscure stories to the screen. Three of the four movies she has made are set in wartime, including her latest, “First They Killed My Father,” based on the true story of Loung Ung, who as a young girl survived the Cambodian genocide and is now one of Ms. Jolie’s close friends.
While Ms. Jolie’s earlier movies garnered tepid reviews, several critics have anointed “First They Killed My Father” her best yet. It is told entirely from the little girl’s point of view, in Khmer, and received a standing ovation at the Telluride Film Festival, where it had its premiere. Netflix was to begin streaming it on Sept. 15, when it will also open in a small number of theaters.
Ms. Jolie said she could not have made the movie had she not first directed “In the Land of Blood and Honey” (2011) about the Bosnian war, and “Unbroken” (2014), based on the true story of an American G.I. taken prisoner in World War II. (She and Mr. Pitt starred together as a married couple locked in a different kind of conflict in her 2015 drama, “By the Sea”).
“It wasn’t a conscious plan of, I was going to make war films, it’s just what I was drawn to,” she said.
Ms. Jolie has an indelible connection to Cambodia, not least because it completely reordered her life. Before first visiting in 2000 to shoot “Lara Croft: Tomb Raider,” she had been a Hollywood wild child, a ravishing Goth weirdo who, at the Oscars that year dressed like Elvira, Mistress of the Dark, and locked lips with her brother. She also got publicly hot and heavy with her second husband, Billy Bob Thornton, and wore a locket with droplets of his blood around her neck.
The grace and humility she saw in the Cambodian people, along with the lasting effects of the genocide, threw Hollywood life into unflattering relief.
“Once you get exposed to what’s really happening in the world, and other people’s realities, you just can’t ever not know, and you can’t ever wake up and pretend it’s not happening,” she said, “Your entire life shifts.”
She adopted Maddox, now 16, from an orphanage, divorced Mr. Thornton, and threw herself into humanitarian and environmental work, finding lasting inspiration in wartime survivors and aid workers.
“The real will to survive, and the strength of the human spirit, and the love of the human family becomes so present, and that’s how we should all be living,” Ms. Jolie said. “When you’re around it, it’s quite contagious, and you know to learn from it.”
The air pressed in hot and close as she spoke, and the sun was climbing its way toward a broiling midday. I was all but keeling over, but Ms. Jolie, who adores the heat, was as composed as a sphinx. (We soon moved to the air-conditioned climes of her kitchen.)
Ms. Jolie is a contained and poised presence, yet also light, breaking every now and then into lilting laughter. She is as visually arresting as she appears onscreen; the sculpted lines of her face alongside the soft O’s of her eyes and mouth make hers an otherworldly beauty. Though slight as a sylph, she says she doesn’t exercise, beyond dipping into the pool with her kids and vaguely intending to someday jump on a treadmill.
Although it was still August, the children — Maddox, Pax, 13, Zahara, 12, Shiloh, Knox and his twin, Vivienne — had already begun home school. They would be accompanying her to the Telluride and Toronto film festivals — Maddox has an executive producer credit on the film — and were making up for lost lesson time, working with tutors in various corners of the house, learning, among other things, Arabic, sign language and physics.
I asked Ms. Jolie if she ever felt like the coach of a small team, and she replied that more often she felt part of a fraternity.
“They really help me so much. We’re really such a unit,” she said. “They’re the best friends I’ve ever had. Nobody in my life has ever stood by me more.”
That last sentence hung in the air, perhaps a subtle allusion to, or indictment of, Mr. Pitt, who adopted Maddox, Pax and Zahara, and is the biological father of Shiloh, Knox and Vivienne. The dissolution of their 12-year romantic partnership came last September, after an incident aboard a private jet — purportedly involving Mr. Pitt and Maddox — prompted her to file for divorce.
Shortly afterward, Ms. Jolie and the kids moved out of Mr. Pitts’s estate, living in a rental for nine months as she struggled with the decision about whether to buy a new home.
“It took me a few months to realize that I was really going to have to do it. That there was going to have to be another base regardless of everything,” she said, her voice falling quiet and low, as it would each time the subject of the split arose. “That there was going to have to be a home. Another home.”
The new house, a Beaux Arts manse that was once the residence of the legendary filmmaker Cecil B. DeMille, is a beaut, with a library, rolling lawns, cascading fountains that burble into the pool, and a view of the Griffith Observatory. Ms. Jolie had an elaborate treehouse built — “more a parkour treehouse,” she said — and the kids helped decorate and pick out the furniture for the whole house. They have an agreement, Ms. Jolie said, that not everyone can agree on everything, but you have to try to like it if you don’t hate it. If you do hate it, you can overrule.
“It has a lot of moments,” Ms. Jolie said of the home, “It’s happy. Happy and light, and we needed that.”
I asked how everyone is doing now.
“None of it’s easy. It’s very, very difficult, a very painful situation, and I just want my family healthy,” she said quietly.
Are they? “They’re getting better,” she said, her voice approaching inaudibility.
She intimated that “First They Killed My Father” might have informed her decision to leave Mr. Pitt. The film centers on Ms. Ung’s family members, some of whom survived, and Ms. Jolie said she thought a lot about what family meant during production, and how they should help each other and take care of one another (the film is adapted from Ms. Ung’s 2000 book of the same name).
“Loung had such horrors in her life but also had so much love, and that is why she’s all right today,” Ms. Jolie said. “That is something I need to remember.”
