Waterworld (1995) – teaser trailer

Set in a future where the polar ice caps have melted and the Earth is covered in water, Waterworld follows The Mariner (played by Kevin Costner), a drifter and scavenger who possesses gills and webbed feet, allowing him to survive in the oceanic world. He becomes embroiled in a conflict between a group of survivors known as the Atoll and a ruthless pirate gang called the Smokers, led by Deacon (played by Dennis Hopper). The Mariner is drawn into a quest to protect a young girl named Enola (played by Tina Majorino), who holds the key to finding a mythical place called Dryland.
