#2 – United 93
In 2006, director Paul Greengrass released this film about a plane hijacked on 9/11. United 93 was the only flight not to reach its intended target thanks to the bravery of its passengers, who worked together to defeat the terrorists. The plane crashed in Pennsylvania, and countless lives were saved by their sacrifice.
United 93 was shot in real time, and ends with the plane crashing to the ground. The fact it really happened makes this movie very painful, but very meaningful, to watch. It is dedicated to the memory of those who died that day.
