This movie that stars Ed Harris, Mary Elizabeth Mastantonio and Michael Biehn, is about a civilian oil rig crew that is recruited to conduct a search and rescue effort when a nuclear submarine mysteriously sinks. One diver (Ed Harris) soon finds himself on a spectacular odyssey 25,000 feet below the ocean’s surface where he confronts a mysterious force that has the power to change the world or destroy it.

Did you know that all of the underwater scenes were filmed in containment tanks at the abandoned Cherokee Nuclear Power Plant in Gaffney, SC? The Containment tanks were built by Duke Power in the mid 1970’s but were never used for their intended construction. In 1986, film producer, Earl Owensby, bought the abandoned facility and converted it into a movie studio.
