Very scary to have been a 'hostage', even if we were only 'acting'.
Much of this film was shot at the old Casablanca airport as Royal Air Maroc has a 737 identical to 'Landshut' (the hijacked plane) which is grounded there. It was repainted in Lufthansa colours, and the cast was confined to the aircraft for up to 12 - 14 hours a day, so the feeling of being 'hijacked' was very real.... no breaks for long periods, very hot, quite an experience for the extras who made up the majority of the passengers.
Also, the whole film of the hijacking was shot 'in sequence' over ten days, and the 'passengers' were not briefed on how the 'hijackers' were going to behave, some of the fear you see is 'real', not acted. Even tho' you know it's just a prop, having a gun waved in your face when you are not expecting it is NOT a nice experience.
And very little make up and so on was used, putting on clothes dirty from yesterday at the start of each days filming really put us in the mood. If the film is as realistic to watch as it was to be part of, then it has to be a really good film - it hasn't come to Maroc yet, so all I've seen of it are the (video) rushes we were shown every evening.
