Angelina Jolie and Brad Pitt are said to be collaborating on another film project which will see them acting side-by-side, according to sources. 

Jolie's upcoming directorship for Africa – a story surrounding brutal elephant ivory poaching and the slow decline of the large mammal – is rumoured to see husband Brad Pitt take the lead role according to sources close to the project. 

The Wrap are reporting today that Pitt will play the main role, in the story which was originally penned by Eric Roth, who also wrote the much-loved Forrest Gump. If the rumours are true, Pitt will take on the character of Richard Leake – who was an avid activist against ivory poaching in Kenya in the Eighties.

The iconic married couple have just finished filming another of Jolie's directorial project By The Sea, which the 39-year-old mother of six also wrote.

"I've felt a deep connection to Africa and its culture for much of my life, and was taken with Eric's beautiful script about a man drawn into the violent conflict with elephant poachers who emerged with a deeper understanding of man's footprint and a profound sense of responsibility for the world around him," Jolie recently noted, explaining her interest in the Africa project.
