Cinematic action horror scene on a stormy Amazon river during heavy tropical rain. A large wooden houseboat with red and blue hull, black tires as bumpers, and railings is violently tossed and tilting in churning, muddy brown floodwaters. A massive, hyper-realistic giant anaconda, over 40 feet long with dark green and black patterned scales, emerges powerfully from the river. The enormous snake coils around the boat, its huge body slamming against the hull and causing massive water splashes. A muscular man in a white t-shirt is thrown overboard and struggles desperately in the turbulent water, swimming and shouting with a terrified expression. The giant anaconda rises dramatically from the water, its head towering over the man, mouth opening wide revealing sharp teeth and pink interior, staring him down in an intense face-to-face confrontation. Dynamic camera angles shift from low water-level shots capturing chaos and splashing waves to dramatic close-ups of the snake's head and the man's fearful face. Moody overcast sky, dense green jungle background, heavy rain, cinematic lighting, realistic water physics, highly detailed, intense action sequence, 11-second dramatic clip, Hollywood movie style, photorealistic.
