Create a cinematic book trailer for “Lord of the Flies” by William Golding. Dark, intense, and dramatic atmosphere, realistic style like a film by Denis Villeneuve or Christopher Nolan. Sequence of scenes: aerial shot of a deserted tropical island, calm and silent ocean. Schoolboys in torn uniforms walking along the beach, disoriented. Close-up of a shiny conch shell on the sand, lifted by a trembling hand. Faces dirty and fearful, eyes lost in despair. Night: around a large fire, boys scream and dance with faces painted red and black, tribal atmosphere. Disturbing close-up: a pig’s head impaled on a stick, swarming with flies. Chaos in the jungle: chases, spears raised, feral screams. Final shot: silhouette of a boy running toward the sea while the island burns behind him, black smoke and towering flames. Color grading: dark, high contrast, natural daylight and fiery orange tones at night. Soundtrack: haunting, tense, building to a dramatic climax.
