The premise for “Waterworld” was clearly explained in an impressive trailer. Narrator James Earl Jones explains that, thanks to climate change, the ice caps at the Earth’s poles have melted, causing water levels to rise around the world, swallowing up any arid land any. Humanity, during the cataclysm, turned to ramshackle floating fortresses, derelict oil tankers and homemade catamarans. By AD 2500, humans had forgotten the land once existed and the world was essentially a post-apocalyptic wasteland much like George Miller’s “The Road Warrior”, just out at sea.
Kevin Costner plays a mysterious train driver known simply as The Mariner, who has a mysterious vase of dirt (rare indeed) as well as a rudimentary bearing set. It’s only been a few centuries, but humanity has been evolving. Waterworld is also home to a tribe of evil pirates known as the Smokers – named for their smoking habits – led by Dennis Hopper.
“Waterworld” will be filmed entirely at sea, an idea that no one less than Steven Spielberg disappointment. Shooting on the water is difficult, and the location leads to many expensive disasters.
First, the multimillion-dollar movie, built in a giant storage tank off the coast of Hawaii, was hit by a hurricane during production, resulting in the entire object sinking to the bottom and need to build a second one. The film’s costs sank, prompting Costner to invest $22 million of his personal cash into production. The sunken setting also made some scenes impossible to shoot, and the final 30 pages were cut from the script. Conventional wisdom suggests that screen time can be 30 minutes.
But despite its own financial commitment, Costner didn’t make things easy during production.
