The Australian actress, known for her breakthrough role as Jordan Belfort's wife Naomi in The Wolf of Wall Street, is in talks to join the new film based on journalist Kim Barker's real life experiences in Iraq and Pakistan.
Barker's 2012 memoir, The Taliban Shuffle: Strange Days in Afghanistan and Pakistan, recalls her time in the war-torn region after first arriving as a correspondent in 2002.
Robbie, 24, will play an ambitious and ultimately ruthless news anchor whom Barker (Fey) meets and befriends in Afghanistan.
The official synopsis for Barker's "darkly comic and unsparing" book explains how she "barely owned a passport, spoke only English and had little idea how to do the 'Taliban Shuffle' between Afghanistan and Pakistan".
Her story exposes the tragedies and absurd events of the 'forgotten war' while finding "humour and humanity amid the rubble and heartbreak".

Directors Glenn Ficarra and John Requa are already on board, after working with Robbie recently on conman drama Focus.
Robbie has also been lined-up for David Ayer's Suicide Squad with Tom Hardy and Will Smith, but will reportedly organise her scheduling for The Taliban Shuffle before committing.
She will next be seen in Focus, due for release in February, while cinema-goers will see her play Jane in Tarzan in 2016.
