Published: March 3, 2026 Last Updated 2 months ago by Faustina Marfo

Wunmi Mosaku is a Nigerian-British actress known for her compelling performances across television, film, and stage. From early British TV dramas to major franchises such as the Marvel Cinematic Universe and her acclaimed role in Ryan Coogler’s Sinners (2025), Mosaku has become recognized as a versatile and respected performer.

Born Oluwunmi Olapeju Mosaku on July 31, 1986, in Zaria, Nigeria, she is currently 39 years old (as of 2026). Her parents, both university professors of Yoruba heritage, moved the family to Manchester, England, when she was just one year old.

Growing up in Chorlton, south Manchester, on a council estate, Mosaku developed a passion for acting early on, inspired by classics like the 1980s musical Annie. She attended Trinity Church of England High School and Xaverian Sixth Form College before pursuing formal training at the prestigious Royal Academy of Dramatic Art (RADA), where she graduated in 2007 with a BA (Hons) in Acting.

Her personal life remains relatively private, but Mosaku has spoken about coming from a matriarchal family focused on protecting, educating, and empowering women. She is married, has a daughter born in 2024, and announced in early 2026 that she is expecting her second child. At 5’8½” (1.74 m), she brings a commanding presence to her roles, often characterized by depth, grace, and quiet intensity.

Early Career and Breakthrough Roles

Mosaku began her professional career on stage after graduating from RADA, with her first credited role in the 2006 production of The Women of Troy. She soon transitioned to screen, gaining recognition for her performance as Joy in the BBC Two miniseries Moses Jones (2009), which marked her rise to prominence.

She next took on a recurring role as Holly Lawson in ITV’s detective series Vera (2011–2012), demonstrating her skill in portraying complex, grounded characters. These early roles established her reputation in British crime and drama, leading to consistent work in UK television.

In 2010, she was recognized as one of the Toronto International Film Festival’s “Super Seven: Fresh Faces” for her role in I Am Slave, further establishing her as an emerging talent.

Acclaimed Performances and Awards

Mosaku’s career advanced with her BAFTA TV Award for Best Supporting Actress in 2017, recognizing her portrayal of Gloria Taylor in the BBC film Damilola, Our Loved Boy (2016). This emotionally significant role made her only the second Black woman to win a BAFTA TV Award in that category at the time.

Her versatility is evident in a range of projects, including Black Mirror’s “Playtest,” The End of the F*ing World, and HBO’s Lovecraft Country as Ruby Baptiste. In the Marvel Cinematic Universe, she played Hunter B-15 in Loki (2021) and reprised the role in Deadpool & Wolverine (2024), adding nuance to the TVA character.

Other notable credits include Det Sgt Catherine Halliday in BBC’s Luther (2019), Riya Ajunwa in ITV’s Passenger, and roles in Batman v Superman: Dawn of Justice, His House (2020), Alice, Darling, and Call Jane.

The Breakout Moment: Sinners (2025) and Award Season Triumph

Mosaku’s career reached new heights with her role as Annie in Ryan Coogler’s 2025 horror-drama Sinners. As a Hoodoo priestess and healer in the Jim Crow-era Mississippi Delta, she delivered a nuanced performance opposite Michael B. Jordan. The film explored grief, spirituality, and resilience, and Mosaku’s portrayal received widespread acclaim for its cultural depth and emotional impact.

The accolades poured in: she won the Gotham Independent Film Award for Outstanding Supporting Performance, the BAFTA Award for Best Actress in a Supporting Role (2026), and the NAACP Image Award for Outstanding Supporting Actress. She received an Academy Award nomination for Best Supporting Actress, along with nods from Critics’ Choice and SAG Awards.

Sinners became one of the most nominated films in Oscar history, and Mosaku’s win at the BAFTAs was a career-defining moment—though she later noted it was “tainted” by an unrelated on-stage incident that affected her celebration.

Her performance in Sinners demonstrated her ability to combine quiet contemplation with profound intensity, drawing on her heritage and personal values. She described working with Coogler and Jordan as transformative and praised Jordan’s kindness and the project’s trust in her vision.

Personal Life, Advocacy, and Future Projects

Beyond acting, Mosaku is a dedicated advocate. She has addressed social issues, including calling for ICE reform at the 2026 Actor Awards (“I need them out”). Her matriarchal upbringing shapes her commitment to women’s empowerment and education.

Her upcoming projects include The Social Reckoning, Aaron Sorkin’s sequel to The Social Network, and the Apple TV+ thriller This Is How It Goes, directed by and starring Idris Elba. This project reunites her with Elba, her former collaborator from Luther.

With a career spanning nearly two decades, Wunmi Mosaku continues to take on roles that challenge norms and highlight underrepresented stories. Her journey from a Manchester estate to Oscar-nominated stardom reflects perseverance, talent, and cultural pride. As a leading Nigerian-British actress in Hollywood, she inspires a new generation while remaining grounded in her roots.
