United 93 (movie)
The roles of one of the flight attendants, the two pilots, and many other airline personnel were filled by actual airline employees. During production, the actors playing the crew and the passengers of the flight were put in separate hotels from the actors portraying the hijackers, even eating their meals separately, ostensibly to create an air of antagonism in the film between the two groups. The set itself was built so that it moved the way the actual flight did. During the filming, many of the actors actually got hurt, and the blood visible on their faces during the revolting scene is authentic and not fake. During the scene where Nami is killed by the passengers in the revolt, he is shown crying. Finishing the very first take, Jamie Harding (who played Nami) was overwhelmed that he was sobbing. In this scene, the sobbing Nami makes as Glick holds him around the head and throat and twists, breaking his neck, is authentic and not acted.
