The document summarizes techniques used in an effective horror movie poster that the author intends to replicate for their own poster. Some of the techniques discussed include: placing the title at the bottom so it is in shadow of the main image; including previous films by the director to appeal to fans; using a single large unnerving main image to set the tone; limiting additional text to avoid revealing too much of the plot; and using a color palette of black and white with subtle red to emphasize mystery and danger. The author analyzes how these techniques appeal to horror movie audiences and effectively advertise the intended tone and content of the film without revealing too much.
