短片黑屋开场（Dreamina 官方 Film #15） prompt

Cinematic intro for a short film: a character enters a dimly lit room, dramatic camera pans, suspenseful music. Subject: a man in his 40s, dark overcoat, weathered face. Action: he pushes a heavy wooden door, steps in slowly, scans the room, stops in the center, exhales. Scene: a derelict study lit by a single hanging bulb over a desk; shadows pool in the corners. Light: hard practical from the overhead bulb, deep ink shadows everywhere else. Camera: slow horizontal pan tracking with him from door to desk, then a soft push-in to medium close-up. Style: noir thriller, 35mm grain, desaturated palette. Audio: low rumbling drone, distant clock tick, no dialogue. Constraints: maintain face consistency, no watermark, no subtitles.
