'Mandela: Long Walk to Freedom' Preview - The Sharpeville Massacre
The life journey of South African president Nelson Mandela is a long and arduous one.

"Mandela: Long Walk to Freedom," a new movie starring Idris Elba as the titular civil rights pioneer, depicts some of the most dangerous and pivotal moments in Mandela's life and political career.

In this exclusive preview, we see one of the those pivotal (and shocking) moments: the Sharpeville massacre. On March 21, 1960, after a day of demonstrations protesting a new law requiring black South Africans to carry papers with them at all times, thousands gathered outside of the Sharpeville police station -- only to be met with gunfire from panicked authorities. Nearly 70 people were killed.

Following the protest, we see Elba as Mandela, burning his papers in opposition to the new law and the murderous actions of the South African police. "We no longer accept the authority of a state that declares war on its own people," he says in a haunting voiceover.

"Mandela: Long Walk to Freedom," co-starring Naomie Harris as Winnie Mandela, opens in limited release on November 29.
