The 50 year-old will also produce the upcoming film, which is based on journalist Michael Hastings' book 'The Operators: The Wild and Terrifying Inside Story of America's War in Afghanistan
Brad Pitt will star and produce in yet another war film.
The 50 year-old is scheduled to play Gen. Stanley McChrystal, who is a former commanding general of international and U.S. forces in Afghanistan.
The upcoming film is called 'The Operators,' and Australian filmmaker David Michod will write and direct it, The Los Angeles Times reports.
Pitt's production company, Plan B, will also produce the film along with New Regency and Brett Ratner's RatPac Entertainment.
The real-life story will be based on journalist Michael Hasting's 2012 book 'The Operators: The Wild and Terrifying Inside Story of America's War in Afghanistan,' which he wrote after researching and following the general for his award-winning Rolling Stone article 'The Runaway General.'
Hastings profiled McChrystal in the music magazine and garnered widespread media coverage after it exposed the general and his staff's criticism of administration officials, President Barack Obama and his advisers, on their handling of the war.
After 'The Runway General' was published, President Obama ordered McChrystal back to the USA and had a one-on-one meeting with him in the Oval Office, the general handed in his resignation.
"The conduct represented in the recently published article does not meet the standard that should be met by - set by a commanding general," Obama said when he announced McChrystal's departure. "It undermines the civilian control of the military that is at the core of our democratic system."
The film will be in good hands as the last film Plan B and New Regency collaborated was for Steve McQueen's historical dram '12 Years A Slave', which went on to win an Oscar for Best Picture back in March.
Hastings died last June in a car crash in Los Angeles, he was 33 years-old.
