Epic cinematic teaser trailer, photorealistic, shot on anamorphic lenses. Opening: extreme wide of a colossal generation ship drifting past a violet nebula, its kilometer-long hull scarred and patched, ion engines glowing faint blue; a deep sub-bass drone under the slow groan of ancient metal. Cut to: interior comms bay — a young officer freezes as a wall of dead analog receivers flickers alive one by one, needle gauges trembling, a waveform blooming across a dusty CRT; through crackling static, a warm human voice hums a lullaby, and the room falls silent around it. Cut to: extreme close-up of the officer's face lit only by green scope glow, a tear tracking down as she leans into the microphone to answer; a single sustained cello note over the tick of a mechanical clock. Final shot: the ship's forward floodlights sweep the void and catch an identical generation ship hanging dead ahead, dark and ancient, mirroring their own silhouette; massive orchestral brass hit, the lullaby returns distorted, hard cut to black with a resonant metallic boom. Cold steel-blue and ember-amber grade, 35mm film grain, volumetric light, ultra-detailed, smooth confident camera movement, trailer pacing, no text, no captions, no watermark.
