Waterworld 2 (2025) | Official Trailer picks up two decades after the events of the original film, diving back into the vast, water-covered Earth where survival is a constant struggle. Kevin Costner returns as the enigmatic Mariner, now a seasoned loner of the seas. Life on Dryland has flourished under the guidance of Helen (Jeanne Tripplehorn) and Enola (Tina Majorino), the latter now a skilled navigator and fearless explorer. But their peace is short-lived.

The story kicks into motion when Enola uncovers an ancient relic—a hidden map suggesting the existence of another fabled Dryland beyond the known world. Determined to explore this new hope and expand the sanctuary for their people, Helen and Enola seek out the Mariner, urging him to join their expedition across dangerous, uncharted waters.

Initially hesitant, the Mariner is compelled by his deep, almost paternal bond with Enola and a restless curiosity about the changing world. Their journey is anything but smooth: monstrous sea creatures, devastating ocean storms, and a brutal resurgence of the Smokers—now led by a cunning warlord (Javier Bardem)—threaten their mission at every turn.

As the Mariner faces the ghosts of his past and confronts what it means to belong, the crew reaches their destination only to find a grim revelation: the supposed Dryland is a scorched, toxic wasteland—another casualty of humanity’s past mistakes. The dream of salvation is shattered, but their return is marked not by despair, but by renewed purpose.

Waterworld 2 closes on a note of resilience and hope, with its heroes more determined than ever to protect the fragile oasis they call home. With sweeping visuals, high-stakes adventure, and emotional depth, this long-awaited sequel reimagines the dystopian saga for a new era.
