Naomie Harris: 'Winnie Mandela had an awful time'

12 July 2013 Last updated at 13:07 BST

Nelson Mandela's autobiography Long Walk to Freedom has finally been made into a film, after 17 years.

The movie Mandela tells the anti-apartheid campaigner's story from his rural upbringing to how he coped with being in prison for 27 years.

Idris Elba took the eponymous role while Naomie Harris played Winnie Mandela - a "controversial and misunderstood" character, as she told BBC Breakfast's Charlie Stayt and Louise Minchin.
