Battaglia con anaconda durante la tempesta.

Cinematic action horror scene on a stormy river with heavy rain and choppy muddy water. A massive hyper-realistic giant anaconda, over 40 feet long with dark green-black patterned scales and huge jaws, erupts from the water beside a small metal boat, mouth wide open with sharp teeth. A terrified man in a beige shirt screams in close-up with wide eyes and panicked expression. On the rocking boat, several people including a muscular man in a black t-shirt and people in yellow raincoats struggle in chaos. The hero grabs a large sharp machete from the wet wooden deck, raises it dramatically, and ferociously attacks the giant snake. Dynamic action shows him stabbing and slashing the enormous anaconda as it coils onto the boat. Intense close-ups capture his determined face and powerful strikes, the snake thrashing violently, and massive water splashes. Low-angle heroic shots show the man standing tall, knife raised, battling the monster in the pouring rain. Dramatic overcast lighting, dense jungle background, realistic water physics, high tension, photorealistic details, intense Hollywood survival action style, 11-second thrilling fight sequence.
