The Dark Glow of the Mountains (1984), suffers from limitations imposed by its subject: the effort of two daredevil climbers to scale two difficult mountains back-to-back, without a break in between. They describe this as something never done before and much more dangerous than climbing one peak. The aesthetic problem, though, is that the available footage was evidently limited to what Herzog shot in conjunction with interviews, and there is no real visual evidence of danger or drama.
The interviews are colorful enough, in their way. One climber boasts that, thanks to frostbite on previous climbs, he is down to four toes; his colleague, perhaps somewhat sheepishly, admits to having all ten, but does note [hopefully?] that, with the difficult project they are undertaking, that could change. Aside from the unique and unprecedented nature of the stunt, and its danger, neither climber cites any particular reason for doing it. The more seasoned of the two—the one with four toes—concedes that he climbs compulsively, and gravitates toward doing new things; unless I’m missing something, that is another way of saying he does it to keep from getting bored. This is quite a jarring contrast to the ski jumping in The Great Ecstasy of the Sculptor Steiner (1974), which Herzog transformed into a mystical pursuit of the transcendent and the poetic. It seems odd to find Herzog, a decade later, celebrating the things mountain climbers do to ward off boredom. And without climbing footage, the film is inert; even the announcement that they have successfully climbed the second mountain registers as curiously flat, almost anti-climactic.
