Roeg's photography reinforces this notion. He is careful to keep us at a distance from the physical sufferings of his characters. To be sure, they have blisters and parched lips, but he pulls up well short of the usual clichés of suffering in the desert. And his cinematography (and John Barry's otherworldly music) make the desert seem a mystical place, a place for visions. So that the whole film becomes mystical, a dream, and the suicides which frame it set the boundaries of reality.
