Dual Personality Cinematic Poster

Vertical split-screen cinematic movie poster with a glowing vertical divide down the center. Left side: [James McAvoy] as a vulnerable, anxious, intellectual version of Kevin from [Split], wearing a neat button-up shirt, with a gentle expression, nervous yet intelligent eyes, warm soft lighting, floating temporal dust particles, and a clean minimalist backdrop with faint clock faces. Right side: [James McAvoy] as the menacing, powerful "The Beast" alter from [Split], shirtless with torn fabric, muscular primal stance, glowing intense eyes, harsh dark chiaroscuro lighting, deep shadows, cracked concrete, broken iron chains, and raw volatile energy. At the bottom, bold text in a fractured futuristic font reads: "[Split — One Mind, Many Realities]". Photorealistic, moody psychological thriller aesthetic, dramatic cinematic color grading.
