Trivia, insights & behind the scenes
The Seattle underground scenes were filmed in the actual abandoned Pioneer Square tunnels, which were still largely untouched in 1973.
This TV movie's success directly led to the Kolchak: The Night Stalker series, which heavily inspired Chris Carter to create The X-Files.
