Sydney Sweeney is officially owning the March 2026 news cycle. Just hours after her “bridal-inspired” appearance at the SXSW premiere of Immaculate, new casting details have leaked for her highly anticipated period drama, The Custom of the Country. The project, which Sweeney is both starring in and executive producing, has added massive star power with the inclusion of Matthew Goode and Louis Garrel.
A Period Drama Powerhouse In The Custom of the Country
Sweeney plays Undine Spragg, a ruthless social climber in turn-of-the-century New York. The addition of Louis Garrel and Matthew Goode suggests that this isn’t just a standard adaptation; it’s being positioned as a prestige awards contender for 2027. This shift toward high-brow drama comes at a strategic time, as the Zendaya and Sydney Sweeney feud continues to dominate headlines, with insiders suggesting Sweeney is purposefully diversifying her portfolio away from teen dramas like Euphoria.
SXSW 2026: The Bridal White Trend
Before heading to the set of her new drama, Sweeney made a “heaven-sent” statement at SXSW. She walked the carpet in a custom Richard Quinn off-the-shoulder gown, featuring a daring corset bodice and sheer over-the-knee lace boots. The look has already sparked a “bridal-white” trend for Spring 2026. This bold fashion choice follows her viral Sydney Sweeney Hollywood Sign Stunt from earlier this year, proving she is currently Hollywood’s most fearless marketer.
Production Leaks and The Housemaid Sequel
Production on The Custom of the Country is reportedly underway in the UK, but that isn’t the only project on Sweeney’s plate. Lionsgate has also greenlit The Housemaid’s Secret, the sequel to her 2025 holiday thriller. With multiple franchises in play, Sweeney is quickly becoming the most productive actress-producer of her generation.
