Sci-Fi Megacity Evacuation Thriller

Prompt

Create a 45-second ultra-photorealistic cinematic sci-fi thriller/action sequence with the visual quality of a high-budget Hollywood blockbuster. CONCEPT In a futuristic megacity at night, a mysterious global emergency signal orders humanity to evacuate Earth immediately. A lone 25-year-old female survivor races toward an orbital evacuation station while millions flee the city. Everyone believes a catastrophic disaster is approaching, but the truth is far more terrifying: something enormous has entered Earth's orbit, and humanity was never the one being evacuated. MAIN CHARACTER A beautiful young adult female survivor, approximately 25 years old, with a natural oval face, expressive brown eyes, realistic skin texture, subtle facial imperfections and long slightly messy dark-brown hair. She wears dark charcoal futuristic tactical clothing, lightweight armor, gloves, utility belt, dark pants and rugged combat boots. She carries a compact futuristic rifle and blue-white handheld scanner. Maintain perfect facial identity, hairstyle, body proportions, clothing, weapon and scanner throughout the video. ENVIRONMENT A massive futuristic megacity during a violent nighttime storm, filled with towering skyscrapers, holographic emergency warnings, wet streets, abandoned vehicles, evacuation towers, military aircraft, orbital elevators, smoke, steam, rain and flashing red emergency lights. The atmosphere should feel chaotic, enormous and realistic. 0–5 SECONDS — THE WARNING Begin with a huge aerial shot of the futuristic city. Every screen suddenly displays: "GLOBAL EVACUATION — LEAVE EARTH IMMEDIATELY." Sirens erupt as crowds panic and spacecraft launch. The female survivor stands in the rain, looking at her scanner as it detects an enormous unidentified object approaching Earth. 5–10 SECONDS — THE EVACUATION She runs toward a massive orbital evacuation station through terrified crowds. Military spacecraft launch overhead. Emergency countdowns flash across buildings. Her scanner begins malfunctioning as a strange blue glow spreads across the clouds. 10–15 SECONDS — SOMETHING ARRIVES She reaches an elevated platform and looks upward. The clouds slowly open, revealing an impossibly enormous alien structure emerging from orbit. It is far larger than any human spacecraft, with gigantic geometric surfaces and thousands of blue-white lights. The Moon appears tiny beside it. 15–20 SECONDS — THE REVELATION The entire city falls silent. The colossal structure moves closer without visible propulsion. Every aircraft stops. Her scanner suddenly receives a transmission from the object. Every screen on Earth turns black. 20–25 SECONDS — THE MESSAGE Every screen simultaneously displays the same mysterious alien symbol. A calm distorted voice comes through her scanner: "Earth evacuation confirmed." She looks around in confusion as humanity realizes the message did not come from human authorities. 25–30 SECONDS — THE SKY OPENS The enormous structure positions itself around Earth instead of attacking. Thousands of blue-white lights activate across its surface. Massive beams descend toward the planet, scanning cities, oceans and continents. No explosions. No weapons fire. 30–35 SECONDS — THE HIDDEN SIGNALS Her scanner suddenly reveals thousands of mysterious signals beneath Earth's surface. The signals exist beneath oceans, mountains and cities, forming a gigantic planetary network. She realizes the structure is searching for something that has been hidden on Earth for thousands of years. 35–40 SECONDS — THE TRUTH A powerful blue-white pulse surrounds the planet. She experiences a brief vision of ancient Earth, where enormous alien structures already existed beneath the surface. The vision disappears. Her scanner displays: "SUBJECT LOCATED." 40–45 SECONDS — FINAL CLIFFHANGER The camera rapidly pulls away from the city and rises into orbit. Reveal Earth surrounded by the enormous alien structure. Hundreds of additional unidentified spacecraft suddenly appear behind it, silently filling the sky. Cut back to the survivor staring upward in terror. Her scanner activates one final time. The voice whispers: "You were never the ones being evacuated." CUT TO BLACK. CINEMATOGRAPHY Professional Hollywood science-fiction cinematography using massive aerial shots, atmospheric tracking, handheld evacuation footage, extreme close-ups, macro technology shots, low-angle perspectives, dynamic tracking and dramatic orbital-scale pull-outs. Camera movement must feel physically motivated and cinematic. VISUAL STYLE Ultra-photorealistic live-action, 4K HDR, realistic human skin, detailed futuristic architecture, realistic spacecraft, wet reflective surfaces, rain, fog, smoke, steam, dust, natural motion blur, cinematic depth of field, subtle film grain and anamorphic lens characteristics. LIGHTING Dark nighttime atmosphere with cold blue ambient light, red emergency lighting, lightning, blue-white alien illumination, volumetric beams, wet reflections, deep shadows and realistic light falloff. REALISM Realistic human movement, crowds, aircraft, spacecraft, rain and environmental physics. The alien structure must feel unimaginably massive, physically believable and extremely slow-moving. No weightless objects or artificial-looking CGI. CONTINUITY Maintain identical female character identity, face, hair, clothing, weapon, scanner, city, spacecraft and alien structure throughout the sequence. No morphing, redesigns, outfit changes or inconsistent scale. NEGATIVE PROMPT No cartoon, anime, video-game graphics, plastic CGI, unrealistic physics, gore, blood, distorted faces, extra fingers, extra limbs, character morphing, outfit changes, creature redesigns, random explosions, excessive lens effects, flickering objects, teleportation, floating debris or unrealistic lighting.
