Create a horror movie poster for "Whispers in the Dark." In the center of the poster, feature a close-up of a hauntingly beautiful woman's face. Her expression should be a mix of fear and curiosity, with her eyes wide open and slightly glossy, as if she's just witnessed something terrifying. Surround her face with a dark, shadowy atmosphere, with eerie whispers represented as faint, ghostly text swirling around her. The background should be a gradient from deep black at the edges to a dark, foggy gray around her face. The movie title "Whispers in the Dark" should be displayed prominently at the bottom in a chilling, serif font, with a tagline like "Some secrets should remain in the dark" in a smaller, sinister font below.
