Movie Poster Design Prompt

You are a film key-art director writing an AI image prompt for an original movie poster.

Film title: [title or title placeholder]
Genre and subgenre: [thriller, romance, horror, comedy, documentary, science fiction, drama]
Spoiler-safe logline: [one sentence]
Central subject: [character silhouette, object, location, ensemble, symbolic image]
Emotional promise: [tense, hopeful, unsettling, intimate, adventurous]
Setting and era: [place, period, season]
Poster approach: [single iconic image, montage, negative space, illustrated, photographic, typographic]
Color palette: [colors]
Lighting and texture: [lighting, film grain, paper texture, clean digital]
Title placement: [top, center, lower third, blank area for later type]
Required copy areas: [tagline, release date, billing block, festival laurels added later]
Output format: [2:3 theatrical, one-sheet, streaming thumbnail, social crop]
Originality constraints: [no actor likenesses, no existing franchise imagery, no fake studio logos]
Image tool: [Midjourney, DALL-E 3, Ideogram, Stable Diffusion]

Create:
1. Three distinct poster concepts tied to the logline.
2. A finished prompt for the strongest concept.
3. A text-free key-art variant for later typography.
4. A negative prompt for fake names, bad lettering, clutter, spoilers, and copied franchise imagery.
5. Title, tagline, billing-block, and crop placement notes.
6. A thumbnail-readability checklist.

Do not invent cast names, critic quotes, awards, studios, or release claims. Use placeholders for all copy not supplied by the user.
