Kling 2.5 Turbo (pro) Prompt: Black and white, silent film style, high contrast, 1920s aesthetic. A serene small lake with a tiny forested island, early autumn. Cozy wooden houses on the shore. Suddenly, a massive nuclear submarine breaks the glassy surface of the water. Water cascades off its colossal hull. The film is grainy, with occasional flicker. A stylized silent film intertitle card appears: "THE NEIGHBORS WERE QUIET... TOO QUIET."
