Sydney Tamiia Poitier has joined the biopic “Robeson” to play Paul Robeson’s wife, opposite “Homeland” star David Harewood and Louis Gossett Jr.

Project is produced by Richard Akel, with shooting starting in September in Montreal. Production companies are Four Stars International and Starling Road Prods., a division of Equinoxe Films.

Variety reported in February that South African director Darrell Roodt was attached to helm the story of the singer, actor and political activist. Gossett plays Robeson’s friend and fellow activist W.E.B. Dubois.

Poitier is the daughter of actor Sidney Poitier. Credits include recurring roles on “Veronica Mars” and “Knight Rider.”

“She’s a delightful person and an accomplished actress,” Akel said. “It also seems rather fitting, in view of the fact that her father knew Paul personally.”

Equinoxe produced and Roodt directed “Winnie,” the Winnie Mandela biopic starring Jennifer Hudson and Terence Howard. Roodt’s credits include “Cry, the Beloved County,” “Yesterday” and “Little One.”

Robeson’s political activism brought him to the attention of Sen. Joseph McCarthy, leading to the revocation of his passport for eight years despite his contributions as an entertainer to the Allied forces during WWII. He married Eslanda Goode in 1921 and she became his business manager.

Poitier is repped by ICM Partners and managed by Thruline Entertainment.
