GRAVITY Monochrome Sci-Fi Movie Poster AI Image Prompt

Epic monochrome science fiction movie poster, vertical theatrical one-sheet, 2:3 aspect ratio. Photorealistic cinematic poster design, high-key grayscale palette, cold white fog, fine film grain, dramatic negative space, clean modern typography inspired by prestige space-survival films. Main subject: one enormous astronaut helmet and upper suit cropped from the left edge, filling the left half of the poster, angled slightly toward the viewer. Helmet details: white hard-surface NASA-like EVA helmet with layered panels, screws, seams, black mechanical joints, reflective visor rim, scuffed metal, two glowing red circular lights on the left side of the helmet. Obscuration: a large opaque square censor block covers the center of the helmet visor and face area; the block is a smooth dark-to-light gray gradient rectangle, positioned center-left, spanning roughly one third of the poster height. Background: misty pale gray outer space with subtle stars and haze; one huge cratered moon or planet dominates the upper-right quadrant, cropped off the top and right edges, bright rim lighting; nine prominent floating asteroid rocks of varied sizes distributed across the lower half and right edge, plus many tiny distant debris specks; one small circular space station or satellite near the lower-right center, with radial modules and solar-panel-like protrusions. Text layout: top cast (5 names: SANDRA HÜLLER, DANIEL BRÜHL, TOM RHYS HARRIES, ACADEMY AWARD WINNER OCTAVIA SPENCER, LÉA SEYDOUX) across the top margin in small condensed uppercase letters; title: {argument name="movie title" default="GRAVITY"} at center-right in very large black ultra-condensed uppercase sans serif letters with wide tracking; credits at bottom center in dense tiny uppercase movie billing block in gray-black, realistic Hollywood poster credits, including lines like 'A FILM BY ALFONSO CUARÓN', 'WARNER BROS. PICTURES presents ...', 'directed by ALFONSO CUARÓN'; website 'gravity-movie.com' below billing block; tagline: {argument name="tagline" default="DON'T LET GO"} at bottom center above release text in spaced uppercase letters; release text: {argument name="release text" default="COMING SOON"} at very bottom center in small spaced uppercase letters; logos (4: Esperanto Filmoj, Heyday Films, soundtrack album on WaterTower Music, Warner Bros. Pictures shield) at bottom strip. Composition: place the astronaut helmet cropped off the left edge, the huge moon cropped off the upper right, the title floating in open space at center-right, and the small satellite and asteroid field below the title; keep the image mostly monochrome with only the two red helmet lights providing color contrast. Customization: lead actor: {argument name="lead actor" default="Sandra Hüller"}, director: {argument name="director name" default="Alfonso Cuarón"}.
