The 29-year-old actress lived in the US during her marriage to pop star Joe Jonas, but returned home to England after their split and doesn't intend to leave her homeland anytime soon.
Turner - who has daughters Willa, five, and Delphine, three, with Jonas - told Flaunt she staying put.
"I just feel so at home here; I never want to move again."
Turner loves that she's surrounded by her friends and family once again.
"Living in the States, I didn't appreciate how much you need friends and family and how integral they are to your wellness until you're away from them. I came back with an abundance of appreciation for them."
Turner plays an actress who hides in a remote cabin after a scandal in Trust, the new thriller film, and the movie star was able to bring her own life experiences to the project.
"I feel lucky to have worked on something that comments on so much that I have been personally affected by."
Turner was also able to lean into her experience of motherhood.
"Being a mother has affected me more than I can ever say. I can now bring so much of that into my work and into this film too."
Turner - who was married to Jonas between 2019 and 2024 - was in the midst of her divorce during the shoot and actually enjoyed being able to throw herself into the project.
"I'm not sure if anyone's aware, but when I started shooting this movie, I was going through, like, a media hell," she said on Late Night with Seth Meyers.
"So this was super cathartic because I wanted to run away in my real life when that was all happening. But I got to do it in a movie and I got to smash some s**t up, so that was fun."
