A realistic cinematic psychological horror film movie poster. Live-action 35mm film still aesthetics with natural film grain, shallow depth of field, and dramatic chiaroscuro lighting. A curly red-haired woman with the recognizable face from the reference portrait, sitting trapped inside a dark, claustrophobic antique room filled with shattered antique mirrors and glowing holographic wireframes reflecting multiple eerie versions of herself. In the dim background shadows behind her, a terrifying, hyper-realistic shadowy entity with elongated pale hands slowly wraps its cold fingers around her shoulders, while parts of the room melt and glitch into an abyss. Her face shows deep, subtle dread and tension. Dark, moody cinematic color grading in teal, amber, deep obsidian, and blood crimson. Authentic movie poster typography integrated at the top: 'ПРОТОКОЛ ДВОЙНИКА', and credits line 'A FILM BY AUTHOR' at the bottom. Photorealistic textures, palpable danger, atmospheric smoke, authentic cinematography, A24 elevated horror style.
