South African filmmaker Darrell J. Roodt (Father Hood and Cry, the Beloved Country) is directing a film called, "Winnie," with the screenplay based on the Anne Marie du Preez Bezdrob biography, Winnie Mandela: A Life. Jennifer Hudon has been cast as Winnie Mandela.
Now, according to Hollywood trade paper, Variety, Terrence Howard has been tapped to play Nelson Mandela, South Africa's first black president and Winnie's former husband. The article at AOL Black Voices' "BV on Movies" blog has more information.
I do remember that there was some controversy in South Africa over the casting of Hudson as Winnie Mandela, and the BV article does mention it. I have to say that I'm not crazy about this casting either, but I look forward to being surprised.
