To commemorate his birthday, a campaign known as "Mandela Day" is asking ordinary people to honor Mandela's legacy by volunteering 67 minutes of their time to charity or service projects. Sixty-seven is the number of years Mandela served his country through public service, politics and prison.

Nelson Mandela's life will make it to the big screen in the coming months.

The movie is expected to be released late November 2013 or January 2014. British Actor Idris Elba will play Mandela.
Over the weekend former South African President Thabo Mbeki was quoted in the South African press as saying,"I am quite certain that Madiba will be discharged. I know the doctors who are working with him (Mandela) are very good people...they're doing an excellent job."
