Wunmi Mosaku is diving into her next project. The Oscar-nominated, BAFTA-winning star of Ryan Coogler’s Sinners has joined the British documentary short Swim Sistas as an executive producer, Variety reported.

Key Takeaways

  • Swim Sistas, directed by Catherine Joy White, celebrates Black women’s relationship with swimming and water.
  • Naomie Harris narrates, voicing Mami Wata, a figure of “ancestral strength and hope for the future.”
  • The film has qualified for the 99th Academy Awards and screened at more than 50 festivals, per Variety.
  • Its makers are developing a documentary series about Black women and water across the U.S., the Caribbean and Africa.

The Full Story

The short follows four Black British women: Alice Dearing, Great Britain’s first Black female Olympic swimmer; rugby player and The Traitors contestant Jasmine Boatswain; teenage athlete Lexie Sandiford; and Roni Bruno, who learned to swim at 54. It features original poetry written by White.

“This powerful film and its themes speak personally to me, as I know it does many others,” Mosaku told Variety. “I believe Swim Sistas will not only move people, but change how they see the world.” BAFTA-nominated producer Ash Horne also joins as an executive producer. Distributor Voce Spettacolo said the film completed its Oscar-qualifying run at the Lumiere Music Hall in Beverly Hills from Sept. 18 to 24.

The Social Conversation

The film sets out to explore the “barriers, histories and joy that shape Black women’s relationships with water,” Variety reported. Mosaku’s name gives it a bigger stage as Oscar season heats up and the series takes shape.
