The new film Mandela: Long Walk to Freedom tells the story of one of the greatest figures of the 20th century. It is the tale of a man who went from being a simple lawyer to a living legend, who rose from prison to the Presidency—all the while preaching about peace. In what is sure to be one of the most talked about performances of the year, Idris Elba will take on the role of Nelson Mandela, and will no doubt wow audiences when the film hits select theaters November 29th.
