Starring: Dwayne Johnson, Jason Momoa, Jason Statham

 “Slow. Heavy. Unstoppable.”

The river wakes up angry. The first trailer for The Hippopotamus crashes onto Africa’s most dangerous waterway, where a classified military experiment has become a weapon of conquest. Nicknamed The Hippopotamus, the colossal amphibious tank—built to dominate land and river alike—is hijacked by a ruthless warlord (Jason Momoa) determined to smash through borders and seize a chain of fortified dam-cities.

Dwayne Johnson stars as the disgraced special-ops engineer who designed the machine, dragged back into the field to fix the one mistake he can’t outrun: his own creation. Alongside him is a lethal, no-nonsense river-patrol commander (Jason Statham), whose mission is brutally simple—hunt it down, or destroy it.

What follows is pure, muscular chaos: gunboat pursuits tearing through mangrove tunnels, underwater demolitions detonating beneath murky currents, and bone-crushing clashes atop a roaring spillway as the river itself becomes a battlefield. With every mile, the stakes sharpen—do they stop the warlord, or make sure The Hippopotamus never belongs to anyone again?

 Loud, relentless, and unexpectedly tense, The Hippopotamus looks like a ferocious collision of war film, heist thriller, and unstoppable-vehicle spectacle—where momentum is destiny, and nothing on the river can stand in its way.
