According to producers, National Geographic photographers Dereck and Beverly Joubert will be on-hand to photograph the elaborate nature sequences for the film.The project has been in the works for quite some time, attracting actresses like Julia Roberts and Kate Winslet. It looks like it’s finally a go with Kidman, as production is scheduled to begin in the first quarter of 2012 in Africa with an eye towards a holiday 2012 release. Mandalay Pictures is currently in negotiations with Universal to handle domestic distribution. Noyce is also attached to direct the thriller The Arrangement and the sci-fi drama Timeless, while Kidman recently acquired the novel The Family Fang which she will produce and star in.
