Trivia, insights & behind the scenes
The monster effects were created by Bill Malone, who later designed creatures for Tales from the Crypt and the 1999 House on Haunted Hill remake.
The film was a direct response to Jaws' success—producers wanted 'Jaws in a mine' but ran out of money for water shots, hence tunnels.
