Clint Eastwood linked to Nelson Mandela rugby drama

The film is to be based on a book by British journalist John Carlin, "The Human Factor: Nelson Mandela and the Game That Changed the World."

It will focus on events surrounding the Rugby World Cup in South Africa 12 years ago and how Mandela used the tournament -- won by the host nation -- to bring whites and blacks together.

Mandela appeared in a South Africa jersey to present the trophy to captain Piennar after the final at Ellis Park in Johannesburg, which has become an iconic moment in the history of the country and sport.
