Clint Eastwood is to direct the heroic true story of three Americans who stopped a terrorist plot on a train bound for Paris.
The as yet untitled project will be based on The 15:17 To Paris: The True Story Of A Terrorist, A Train, And Three American Heroes, the book written by the three men.
Anthony Sadler, Alek Skarlatos and Spencer Stone were on a European holiday in Paris when an attacker entered the train they were in, shooting an automatic rifle.
“I just looked at Spencer and said, ‘Let’s go!’,” said Mr Skarlatos at the time.
“Spencer got to the guy first, grabbed the guy by the neck and I grabbed the handgun, got the handgun away from the guy and threw it,” he added.
“Then I grabbed the AK, which was at his feet, and started muzzle thumping him in the head with it.”
One of the friends was in the Oregon National Guard and another in the US Air Force.
They were hailed as heroes both in the US and France, where they were awarded the Legion of Honour.
They charged and overpowered 25-year-old Moroccan national Ayoub El Khazzani, who had enough ammunition to kill 500 people.
The movie follows a pattern in Eastwood’s recent output of recounting real-life stories of American heroism.
It comes after his 2014 hit American Sniper, about Navy SEAL sniper Chris Kyle, and last year’s Sully, about “Miracle on the Hudson” airline pilot Chesley Sullenberger.
There is no casting yet, and no details on when the project will begin production.
