Sienna Miller’s 2025 Renaissance: From New HBO Series to Motherhood Advocacy

A New Chapter in Television
Sienna Miller is set to star alongside Dominic West in ‘War’, a groundbreaking legal thriller that has secured a two-season commitment from HBO and Sky. In this compelling drama, West portrays tech titan Morgan Henderson, while Miller takes on the role of his estranged actress wife Carla Duval.
Advocacy and Personal Growth
Miller has recently emerged as a powerful voice for women’s rights, particularly regarding motherhood at different ages. The actress, who welcomed a child at 41 with her partner Oli Green, has been vocal about the double standards women face when choosing to have children later in life, describing such judgments as ‘misogynistic’ and ‘anti-feminist.’
She has notably pointed out the societal double standard, referencing how male actors like Al Pacino and Robert De Niro, who have had children in their 80s, face far less scrutiny. Miller has been particularly candid about this disparity, mentioning these actors who are also her friends.
Fashion and Cultural Influence
In 2025, Miller continues to influence fashion trends, delivering masterclasses in laid-back, city-ready chic. She consistently demonstrates that comfort and style can coexist while maintaining her signature fashion DNA. Her recent collaboration with Frame has garnered attention, with Miller and Green co-hosting an event at Chateau Voltaire in Paris during Fashion Week.
Upcoming Projects
Miller is also featuring in ‘My Mother’s Wedding’, directed by Oscar nominee Kristin Scott Thomas, set for release on August 8, 2025. The heartfelt comedy follows three sisters returning to their childhood home for their mother’s third wedding, with Miller starring alongside Scarlett Johansson and Emily Beecham in this exploration of family dynamics and relationships.
