Winnie Mandela no fan of planned biopic starring Jennifer Hudson

And Winnie Mandela is telling you, Jennifer Hudson, that she doesn't want this movie going forward.

The ex-wife of South African leader Nelson Mandela has taken issue with "Winnie," an upcoming biopic starring Hudson and Terrence Howard. Reports say Mandela, maiden name Madikizela, isn't fond of how she's painted in the script.

"We don't shy away from the controversies," said director Darrell Roodt, adding that the film is "not for Winnie Mandela, it’s about Winnie Mandela."

Though the matriarch's lawyers fear the project is a veiled "character assassination," the film producers insist the two-and-a-half-month shoot will start May 31.

"If it wasn't for Winnie Mandela, South Africa would have been a vastly different place...it's the ultimate women's movie," Roodt said.

The real Winnie isn't a happy camper, but Hudson herself was all smiles in Cannes on Sunday, looking svelte and happy at a photo call for the flick, with costar Howard in tow.
