'Good Morning, Mr. Mandela' film in the works

A film adaptation of "Good Morning, Mr. Mandela", book written by Zelda la Grange, the former private secretary of Nelson Mandela, is in development. The book is based on her friendship with the former South African president.

The film will be produced by Maven Pictures and Jacqui Lewis.

Grange grew up surrounded by people who perceived Mandela as a terrorist but she eventually served as one of his most devoted associates for almost two decades.

She began working in Mandela's office as a typist in 1994, when he was elected as the post-apartheid president, and was promoted in 1999 to the post of private secretary to the office of the president, reports variety.com.

Director or actors for the film are yet to be finalised.

Mandela died in late 2013, shortly after the release of the film "Mandela: Long Walk to Freedom", starring Idris Elba and Naomie Harris. That film was based on the 1995 autobiography "Long Walk to Freedom", published by Mandela.

Mandela was also portrayed by Morgan Freeman in the 2009 film "Invictus" opposite Matt Damon.
