This poster follows horror movie conventions with its use of red, black and white colors. It features a young blonde girl dressed in white, representing innocence, with blood trailing behind her and a face made of blood in the background. The title "Sinister" stands out in bold black writing against a white background. The names of popular horror movies produced by the same company are included to attract audiences. The tagline "once you see him, nothing can save you" creates a threatening and personal tone. Snakes below the blood face further indicate this is a supernatural horror film. The poster stylizes and positions elements to draw in viewers through mystery, fear and promises of danger.
