Nelson Mandela. His name alone connotes an image of strength and fierce conviction. But it’s difficult to express in any simple sentiment the various ways in which this brave political leader changed the face of politics, both at home in South Africa and around the world.

On November 29, less than a week before Mandela’s passing, Idris Elba stepped into the role of the man who would eliminate apartheid in his home country in Justin Chadwick’s Mandela: Long Walk to Freedom, an adaptation of Mandela’s 1994 autobiography, Long Walk to Freedom, which the late activist wrote while he was in prison. The film was met with much praise following its premiere at the Toronto Film Festival in September, with Variety critic Scott Foundas noting that “Idris Elba gives a towering performance, a Mandela for the ages.”
