Idris Elba joined Winnie Mandela, the ex-wife of former South African president Nelson Mandela, and her daughter Zindzi Mandela, at the premiere of Long Walk to Freedom in Johannesberg.
Elba plays Nelson Mandela in the film which is expected to be released in the UK on January 3.
Winnie Mandela has told ITV News that the allegations against her of kidnap, assault and murder were "manufactured by the system I was fighting against".
The former wife of Nelson Mandela said that such accusations were "water off a duck's back," adding that "when it suits the media, I am a murderer".
The former wife of Nelson Mandela has told ITV News that she has a "great relationship" with his current wife, Graca Machel.
In an interview with Mark Austin, Winnie Mandela said that the pair refer to each other as "big sister" and "little sister" and even confided that they moan together about the former president of South Africa.
Nelson Mandela's former wife, Winnie Mandela, has said that she will always love her ex-husband because he is the father of her children.
Speaking exclusively to ITV News, she said: "No mother can say they hate their partners no matter what the social situation is between them."
