Chastain was struck by Turner’s poise when she met her before shooting began. But she also sensed the uncertainty of an actor transitioning into a higher-profile phase of her career. “There was this idea of like, What am I allowed to do? What am I allowed to say? Who am I allowed to be?” Chastain said. “It’s really exciting for me to see Soph understand that everything that’s happening to her is because of her — she created this.”

For Turner, her trajectory is not unlike that of any young adult stepping out into the world. “It feels like ‘Game of Thrones’ was secondary school; now ‘X-Men’ is university,” she said.

Her “Thrones” pack scattered to the winds, Turner has created a new one with Jonas, whom she married earlier this month in a surprise ceremony in Las Vegas. (They had been engaged since 2017.) An Elvis impersonator presided; Diplo posted video to Instagram.

“I take a lot of inspiration from him,” she said of Jonas. “He went through a breakup with his band, who are also his brothers, and that’s got to be really, really difficult. For him to have a wonderful family life and wonderful relationships with his brothers, and still turn out to be a very grounded normal person, is astounding to me.”

The band is back on tour this summer, and together the couples form an extraordinarily attractive and talented group of young people doing young people things — hitting the slopes in Switzerland, pouring body shots upon gobsmacked Penn State students. But to Turner, there’s nothing extraordinary about it. “It just feels normal to us,” she said.

The paparazzi, she insists, are only there for Jonas. “I’m just like a tag-along,” she said, which is patently ridiculous. But the upshot is that even now, even in New York, she’s still bombarded with her image more than she’d like. “Social media just sucks,” she said.
