Clint Eastwood is planning a film adaptation of the 2015 terror attack thwarted by three Americans on a European train, according to The Hollywood Reporter. The film will reportedly be based on the book “The 15:17 to Paris: The True Story of a Terrorist, a Train, and Three American Heroes,” written by Jeffrey E. Stern and Anthony Sadler, Alek Skarlatos and Spencer Stone, the three passengers lauded as heroes after their quick thinking foiled a potential terrorist attack. The three California natives, Skarlatos an Oregon National Guardsmen and Stone a U.S. Air Force Airman, were traveling through Europe on a train bound for Paris when shots rang out near the border of Belgium and France. The trio was able to overpower the suspect, a Moroccan national who was armed with a handgun, an automatic rifle and a knife. Their bravery was later honored internationally with several ceremonies and a flurry of press.
