Damon and Eastwood Join Freeman For Nelson Mandela Movie Clint Eastwood is set to direct a script based on the true-life events documented in the book, The Human Factor: Nelson Mandela and the Game that Changed the World by John Carlin. Matt Damon will play star rugby player Francois Pienaar who befriended Nelson Mandela (who, as we learned a while back, will be portrayed by Morgan Freeman) during the run-up to a game that "gave whites and blacks in South Africa a common cause to rally around as the country was trying to heal from the wounds of apartheid."
