Mia Threapleton is stepping into the global spotlight as the lead in Wes Anderson’s new film The Phoenician Scheme, premiering at the 2025 Cannes Film Festival. The 24-year-old British actress, best known for her television work in The Buccaneers, takes on the role of Sister Liesl, marking her highest-profile role to date.

Directed by Anderson and set in Europe, the film features a cast of returning collaborators and new faces, including Benicio del Toro, Michael Cera, Tom Hanks, Scarlett Johansson, and Bryan Cranston. Threapleton plays a headstrong daughter caught in a caper involving her estranged father, an eccentric land scheme, and a string of near-fatal events. Threapleton’s casting signals a potential breakout moment, though audiences may already recognise her surname - she is the daughter of Oscar-winner Kate Winslet.

Threapleton recently worked alongside her mother in I Am Ruth, a drama that earned Winslet a BAFTA. The Phoenician Scheme debuts at Cannes this month along with theatrical release on May 30.
