In August 2015, on a high-speed train in France, three American friends, two of them off-duty members of the US military, thwarted a terrorist attack after a man armed with an assault rifle and other weapons tried to open fire in the train. Four people were injured, but there were no fatalities.
The three Americans instantly became heroes and wrote a book about their ordeal, which has now inspired a movie directed by Clint Eastwood.
This all sounds like standard protocol for an incredible act of bravery like this, but it gets more interesting: Eastwood cast the three real-life friends who stopped the attack to be the leads in the movie.
"The 15:17 to Paris," which is also the title of the book about the attack, is Eastwood's latest based-on-a-true story movie (American Sniper, Sully), and in telling this one he has Airman 1st Class Spencer Stone, Specialist Alek Skarlatos, and Anthony Sadler reenacting their heroics (Stone sustained injuries while taking down the gunman).
The trailer was released Dec. 13 and looks beyond the acts on that August day, showing how the friends got to that moment in their lives through flashbacks of their childhood and Stone and Skarlatos' military service.
Watch the trailer below. It's quite inspiring. Warner Bros. will release the movie on Feb. 9.
