Kristin Scott Thomas on Her Directorial Debut, 'My Mother’s Wedding'

When perusing Kristin Scott Thomas’ impressive C.V. of film, television, and theater roles, it’s very clear that she’s the rare performer who’s been able to maintain a certain je ne sais quoi through the entirety of her career. She exudes a worldliness while being vulnerable, yet comes across as whip smart and still accessible. Perhaps her mystique is due to her gift for playing aloof so well, or her four decades of residing in France, where maintaining a sense of privacy is highly valued. Or maybe, Thomas was just deemed forever exceptional from the moment Prince hand-picked her to star in his 1986 directorial debut, Under the Cherry Moon (now a cult fav).

But Thomas has worked hard to earn her status as a well-regarded thespian. One brave enough to tackle Chekhov on the stage many times, and can also turn a supporting role in Four Weddings & a Funeral (1994) or lately as M15 spook Diana Taverner in Apple TV+’s Slow Horses into something very memorable, indeed.

Not one to rest on her laurels, in 2022 Thomas decided to co-write, direct, and act in her first original feature film, My Mother’s Wedding (out in U.S. theaters starting Friday, August 8, 2025). She cast herself as Diana, the matriarch to three adult daughters — played by Scarlett Johansson, Sienna Miller, and Emily Beecham — all of whom are still wrestling with their childhood traumas and current messy personal lives as they visit their mother for her latest marriage. Thomas also infused some of her own history, weaving in her personal experience of losing her father and her stepfather to separate aviation accidents when they were pilots for the Royal Navy.
