The 15:17 to Paris movie billboards...

This Friday Clint Eastwood will bring the real-life story of the thwarted terrorist attack on the high speed Thalys train #9364 bound for Paris on August 21, 2015, to life on the big screen.

Adapted from Jeffrey E. Stern's autobiography, The 15:17 to Paris: The True Story of a Terrorist, Train and Three American Soldiers, the film tells the story of the three American friends who bravely confronted and subdued a gunman armed with an assault rifle on a crowded train bound for Paris from Amsterdam Centraal station.

To make the retelling even more realistic, the three men Spencer Stone, Anthony Sadler and Alek Skarlatos, will play themselves in the movie.

These movie billboards were photographed along Westwood Boulevard, Sunset Boulevard, Beverly Boulevard and Pico Boulevard from January 15 to January 21, 2018.

As Edmund Burke said, "The only thing necessary for the triumph of evil is for good men to do nothing", so let's be thankful that these good men acted they way they did to stop what would have been a senseless massacre otherwise.
