The production standards of this film are stunning, including a quarter of a mile wide floating artificial atoll constructed especially for the movie and regularly manoeuvred so it always pointed out to sea.
Kevin Costner is the Mariner, a mutant that can breath under water and lives on an astonishing trimaran controlled by complex lever and pulley mechanisms and other wonderful improvisations. He is later joined by Helen (Jeanne Tripplehorne) and Enola (Tina Majorino) a great performance from a ten year old girl.
The villain is Deacon (Dennis Hopper) and as a fan of his in other films I query his casting in this role, he is just too over the top for the rest of the film, the contrast is so great it brings an unfortunate taste of “Treasure Island” (including an eye patch) which jars.
However the environment of a world overwhelmed with water was not well thought out, some examples, where did all the petrol come from for the water skies, why is everyone so hungry when the seas must have been teaming with fish, the Mariner and Helen would have been crushed to death during the descent to the bottom of the ocean, with so much water why is there never aly rain.
With special effects, stunts and gadgets that are stunning, great photography and direction, this film is well worth watching if it takes your interest.
