“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.”

Determined to make the film as Cambodian as possible, Ms. Jolie teamed with the Cambodian director Rithy Panh, who received an Oscar nomination for his 2014 documentary, “The Missing Picture,” and enlisted thousands of Cambodians as extras. Ms. Jolie said Maddox was her right-hand man, working on the script, taking meeting notes and bantering with Mr. Panh in French. Some of the scenes were shot on massacre sites, so the crew arranged for monks to pray and set out incense and offerings beforehand.

“She is very loved there,” said Mr. Panh, who served as a producer on the film. He added that he was struck by Ms. Jolie’s humility, and how she intuitively communicated with the children on set, despite her shaky grasp of the Cambodian language. (Ms. Jolie said a suggestion in Vanity Fair that children were cruelly hoodwinked in the casting process was “a mischaracterization”).

Ms. Ung said Ms. Jolie, who has Cambodian citizenship, shares her countrymen’s sensibilities. “In Cambodia you don’t raise your voice, you speak kindly to people, you greet people with your hands together and bow,” Ms. Ung said, “All of this comes naturally to her.”

As our interview wrapped, Ms. Jolie joked that she would next work on a comedy. “I will get funny at some point,” she said, adding that she was working on “Maleficent 2,” a sequel to the Disney fractured fairy tale. “That was a little funny,” she said, wryly.

Ms. Jolie also seemed aware of how she might be beheld by the public; the removed ice queen to Mr. Pitt’s affable down-home Missouri boy (his revealing interview in the summer issue of GQ Style helped burnish his image as the more relatable one). But she grew up a punk in school, she said, and was used to not fitting in, and being someone people had opinions about.

“I never expect to be the one that everybody understands or likes,” Ms. Jolie said, walking me down her driveway, “And that’s O.K., because I know who I am, and the kids know who I am.”

She quickly embraced me goodbye, and I set off into the sun and the heat, as the heavy security gate slowly drew shut behind.
