Factual errors: At the mountaintop exchange scene, not one of the actors seems to be effected by the considerable down-force caused by the still spinning rotor blades of the helicopter as they get out of it. Even Fenn's shoulder-length hair moves only slightly and the snow beneath their feet seems completely unperturbed by the wind caused by the helicopter. A helicopter touching down in a snowy location would cause a small blizzard and anyone getting out would at the very least be hunkered down and making some attempt to cover themselves from the wind and snow, rather than casually strolling along.
