Nine Miles Down

Nine Miles Down is a 2009 horror film that based on the widespread urban myth started in the early 90s surrounding the claim that Russian scientists in Siberia had drilled so deep that they had broken through into hell and recorded the screams of the damned emanating from the borehole. This claim turned out to be a hoax spread by a Scandinavian prankster who wanted to demonstrate human gullibility. However, by the time he owned up to the prank, the myth had fueled such a following, that his retraction was interpreted as an attempt to cover up the truth. It was the last feature film credit for renowned writer Everett de Roche.

In 1995 Nine Miles Down was in preproduction with Spelling Productions with Thom Mount as producer and John Carpenter slated to direct. John Carpenter left the production to make Escape from L.A. 1996 and Spelling lost the project.
