The document discusses conventions used in horror film marketing including posters, trailers, and magazine covers. For posters, common elements are a large title, attention-grabbing main image relating to the sub-genre, a memorable tagline without revealing too much of the plot, and production details. Trailers typically show normality at first, then a disruption, followed by fast-cut intense clips, title/release text, and a shocking ending sting. Magazine covers feature the masthead, main film title and sell image dominating the cover with additional article photos and brief descriptions.
