'United 93' and 'The Bourne Supremacy' director Paul Greengrass is to write and direct a new film about the aftermath of the 2003 invasion of Iraq.

Variety reports that the film will be based on Rajiv Chandrasekaran's book 'Imperial Life in the Emerald City: Inside Iraq's Green Zone'.

Chandrasekaran served as the Washington Post's Baghdad bureau chief from April 2003 to October 2004.

Shooting on the film is scheduled to begin later this year when Greengrass completes work on 'The Bourne Ultimatum'.
