Waterworld (1995)

The sun. For millions of years the source of life. But for one planet the source of it's demise. The temperature climbed, the vast pools of ice at it's poles melted, and the oceans rose. Centuries later, few people remained on this planet, once called Earth. A lone mariner sails the expanse of water, trading to survive. For survival, is all these people do, in this place they know only as Waterworld.
