The film was shot by the filmmakers in color, but with a bleak, cold, and severe look so as to appear as if black and white, but with traces of color added. According to the Alaska Roads website, "this, they felt, would highlight the contrasting majesty of the Alaskan mountain wilderness, with its bleak trees and black rocks against the white of its snow, and it also heightened the image of the monstrous black train hurdling down the tracks under the bright white sky."

Alternate Versions

The DVD mysteriously edits out the shot of the first helicopter policeman being run over by the wheels of the train. You see him crash into the train windshield and see him fall off, but then you see just a plain shot of the wheels. In all other versions of the film on video and laserdisc have a shot of this man's face coming right at the camera as his body is run over by the wheels of the train. Even the US TV version has a brief shot of this. This shot is present in the UK Arrow Films DVD release. See more
