'The Abyss' is a 1989 science fiction film written and directed by James Cameron. It stars Ed Harris, Mary Elizabeth Mastrantonio, and Michael Biehn. The original musical score was composed by Alan Silvestri. It was released on August 9, 1989 in North America.
Underwater scenes were filmed in the containment building of Cherokee Nuclear Power Plant, an unfinished nuclear power plant on Owensby Road, near Shelby, North Carolina, in the United States. It took seven million gallons (27 million liters) of water to fill the tank to a depth of 40 ft (12.2 m), making it the largest underwater filming set ever constructed. The depth and length of time spent underwater meant that the cast and crew sometimes had to go through decompression. Filming was also done at the largest underground lake in the world - a mine in Bonne Terre, Missouri, which was the background for several underwater shots.
