Attaque d'anaconda géant

Cinematic action horror sequence during a heavy tropical rainstorm on a murky Amazon river. A large two-story wooden houseboat navigates choppy waters as a gigantic hyper-realistic anaconda, over 50 feet long with dark green and black patterned scales, swims powerfully alongside before launching a massive attack. On the wet deck, panicked passengers react in terror: a woman in a white shirt runs screaming, a muscular man in a black shirt points and shouts, a young girl in a colorful tie-dye hoodie screams with fear, and an older man with white hair gestures desperately. The enormous anaconda rises from the water, coils its massive body around the boat, slams into the hull, and violently overturns the vessel, causing it to tilt dramatically and capsize amid huge splashing waves. Dynamic shots include aerial views of the snake beside the boat, chaotic deck panic with rain pouring down, close-ups of terrified faces, and epic wide shots of the giant serpent wrapping and destroying the houseboat. Dense jungle backdrop, stormy overcast lighting, realistic water physics, intense Hollywood blockbuster style, photorealistic details, high-tension survival horror, 10-second dramatic action clip.
