W as in Waterworld (1995)
(Wikipedia) An antihero, known only as "the Mariner" (Kevin Costner), is a drifter who sails the Earth in his trimaran. He comes into an atoll seeking to trade his dirt, which is now a precious commodity. There, it is revealed that he is a mutant with webbed feet and gills, a new step in evolution to accommodate the changes in climate. The atollers, fearful of him, vote to "recycle" him by drowning him in a yellow sludge-like brine pool. At this moment, pirates known as "Smokers" arrive in a raid on the atoll, as they have been tipped off by a Smoker spy posing as a trader (Gerard Murphy), known as "the Nord."
