 When the sandstorm initially hits at the nagada village and Kurt Russell,   James Spader and the others are locked inside the city, they decide that   they do not want to stay and decide to leave; when the natives try to stop   them Kurt Russell shoots at the ground to frightem them off. The boy (whom   he later befriends) takes him up above to see the sandstorm approach. After   this, a native that they were holding at gunpoint is released and Jackson   comments "Sandstorm, that would have been a brilliant reason to shoot   everyone".
