Bloody Sunday director Paul Greengrass marks the five-year anniversary on
the Sept. 11, 2001, terrorist attacks on the United States with this largely
speculative meditation on the events that took place onboard the fourth hijacked
plane, and the heroic actions of the passengers who gave their lives to ensure
the safety of others. Told in real time and acted out by a cast of unknowns who
were provided with detailed studies of their real-life counterparts, United 93
attempts to reconstruct the airborne tragedy from the view of the ground and
flight controllers, the passengers, and their nervous families awaiting word on
the fate of their loved ones. As the terrified travelers and crew gradually
become aware of the historical events taking place on the ground so far beneath
them, the 90 minutes in which a random collection of strangers realized their
fate and came together to confront an unthinkable threat are re-created. ~ Jason
