Dual-Personality Cinematic Poster

Create a high-quality vertical split-screen cinematic poster with a glowing vertical divide down the middle. Left side (lighter, more vulnerable personality): actor as a soft, anxious, intellectual version of Kevin from the movie movie. Neat button-up shirt, gentle expression, warm lighting, slightly nervous but intelligent eyes, subtle time particles floating around him, clean minimalist background with faint clock faces. Right side (dark, intense personality): actor as the powerful, menacing "The Beast" alter from Split. Shirtless or torn clothing, muscular and primal pose, intense glowing eyes, dramatic dark lighting with strong shadows, cracked concrete and broken chains, raw powerful energy. Bold text at the bottom in fractured futuristic font: “title”. Ultra-detailed, photorealistic, cinematic color grading, moody thriller atmosphere, 8k quality.
