OHANNESBURG (AFP): A film based on the life of Nelson Mandela, “Long Walk to Freedom”, has became South Africa’s all-time highest grossing picture after its opening last week, production company Videovision Entertainment said Tuesday. The British-South African co-production, starring British actor Idris Elba as Mandela, has earned 4.4 million rand ($427,000, 315,000 euros) - shattering records previously held by blockbusters like “The Wolverine”, “Hangover 3” and some locally produced films.
