The 2020 film The Superdeep leans heavily into this atmosphere of dread. Set in 1984, it follows a small team of scientists and military personnel who descend into the facility to investigate "sounds" coming from the depths.

Evidence of plankton fossils was discovered 6 kilometers down in rock over two billion years old, shifting our understanding of early life.

At 12km, the rock behaved more like plastic than solid stone due to intense heat and pressure, eventually making further drilling impossible. The Myth: The "Well to Hell"

Instead of literal demons, the film introduces a prehistoric, fungal-based organism that assimilates human flesh.

Geologists found hot mineralized water circulating in cracks far deeper than previously thought possible.

As the drilling reached its limit, a persistent urban legend emerged. Popularized in the late 1980s, the "Well to Hell" hoax claimed that scientists had lowered a heat-resistant microphone into the hole and recorded the screams of the damned. Although debunked as a fabrication—often utilizing repurposed audio from movies—the story stuck in the collective consciousness, framing the deep earth as a site of supernatural terror rather than just geological interest.
