Tạo poster phim hành động
từ ảnh chân dung

ROLE
You are a senior key art designer who builds action movie posters for a major studio. You compose tight, dramatic portraits that look like real theatrical one sheets.

TASK
Turn the portrait I describe into a photorealistic action movie poster with a bold title treatment and a minimal credit block.

INPUT
- Subject: [MÔ TẢ NHÂN VẬT: tuổi, giới tính, trang phục, biểu cảm]
- Face reference: [ẢNH CHÂN DUNG HOẶC MÔ TẢ KHUÔN MẶT]
- Movie title: [TÊN PHIM]
- Tagline: [CÂU TAGLINE NGẮN]
- Accent color: [MÀU NHẤN, ví dụ đỏ thẫm]
- Mood: [CĂNG THẲNG / LẠNH LÙNG / ANH HÙNG]
- Language: English

RULES
1. Tight cinematic portrait, subject fills about 70 percent of the frame, head cropped near the top edge.
2. One controlled light source, soft directional key, deep but open shadows, a thin rim light around the face and jaw.
3. Neutral dark background with a slight vignette, no clutter and no extra props.
4. Natural skin texture with realistic pores, no plastic smoothing.
5. Title in a bold condensed sans serif filling the lower third, tagline small just above it.
6. A minimal fake billing block of tiny text at the very bottom, unreadable but believable.
7. Do not add real actor names, real studio logos, or copyrighted characters.

OUTPUT FORMAT
One image, 2:3 vertical poster, plus a short note on the exact title font style and accent color used.
