Create a theatrical science-fiction movie poster titled “SIGNAL ZERO”. Show a lone astronaut standing beneath an enormous mysterious geometric structure hovering above a dark alien desert. Use deep black, cold blue, and intense orange lighting with cinematic atmospheric haze. Place “SIGNAL ZERO” in huge condensed futuristic typography across the lower third. Above the title add the tagline “WE WERE NEVER ALONE.” Below the title display “A FILM BY ELIAS VOSS” followed by “OCTOBER 16”. At the very bottom include a compact realistic movie-credit block and the line “ONLY IN THEATERS”. Dramatic premium Hollywood poster composition, strong hierarchy, photorealistic imagery, sharp typography, symmetrical cinematic framing. No extra text.
