What we see in this film is the affect Mandela had on all types of people, in this case a white man who was his guard in different ways over many years who was forced to hate the South African blacks and believe that the Apartheid was right, good and even approved by God! However deep inside he was torn simply because his best friend, when he was a child, was black. By playing with his friend he learnt one of the black languages, which is how he became Mandela's guard in the first place.
Despite this film being a true story which in my opinion always makes films greater, I didn't think this film was a great film because it doesn't reveal much about Mandela's personality, but it is good. I would definately recommend it because it inspired me. Thanks to this film I found out about the South African Freedom Charter.
