The Split Within: One Mind, Many Faces

Create a high-quality vertical split-screen cinematic poster with a glowing vertical divide down the middle.

Left side (lighter, more vulnerable personality): James McAvoy as a soft, anxious, intellectual version of Kevin from the movie Split. 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): James McAvoy 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, subtle glowing time glitches and timeline fractures in the air.

Clean glowing vertical split with subtle clock motifs. Bold text at the bottom in fractured futuristic font: “Split — One Mind, Many Realities”

Ultra-detailed, photorealistic on the right, slightly stylized on the left, cinematic color grading, moody thriller atmosphere, 8k quality, masterpiece, dark psychological tone with subtle time-guardian elements. 

Professional cinematic style, fully appropriate, focus on acting performance and psychological intensity, no excessive violence.
