Waterworld is a 1995 American post-apocalyptic science fiction action film directed by Kevin Reynolds and co-written by Peter Rader and David Twohy. It was based on Rader's original 1986 screenplay and stars Kevin Costner, who also produced it with Charles Gordon and John Davis. It was distributed by Universal Pictures.
The setting of the film is in the distant future. Although no exact date was given in the film itself, it has been suggested that it takes place in 2500. The polar ice caps have completely melted, and the sea level has risen over 25,000 feet, covering nearly all the land. The film illustrates this with an unusual variation on the Universal logo, which begins with the usual image of Earth, but shows the planet's water levels gradually rising and the polar ice caps melting until nearly all the land is submerged. The plot of the film centers on an otherwise nameless antihero, "The Mariner", a drifter who sails the Earth in his trimaran.
