One of the locations used for the filming of the 1989 science fiction film ' The Abyss ' was Cherokee Nuclear Power Plant , an uncompleted nuclear power plant on Owensby Road, near Gaffney, South Carolina. There, director James Cameron constructed the largest underwater filming set ever built. It took 7 million US gallons (26,000 m3) of water to fill the tank to a depth of 40 feet (12 m).
