Gemini Prompt: A cinematic 15-second vertical 9:16 video set in Mumbai in the year 2050, at night during heavy monsoon rain. A lone young man walks slowly down a futuristic Mumbai street, seen from behind. Massive futuristic skyscrapers rise around him, glowing neon lights and holographic advertisements reflect on the wet road. Flying taxis smoothly pass between the buildings overhead. Mumbai feels dense, alive and futuristic, with subtle Indian architectural elements. Camera slowly follows the man from behind at street level, realistic rain falling, water splashing under his shoes, atmospheric fog, dramatic cinematic lighting, photorealistic, ultra-detailed, believable near-future technology, emotional sci-fi movie atmosphere.
