The document discusses conventions of horror film posters. It notes that horror posters typically use low lighting to create mystery and a sense of isolation. Fonts are often bold or in an informal, child-like style to appear unsettling. Posters may feature protagonists or villains without too many identifiable details to generate intrigue. Common colors include dark tones like black, red, and grey that convey danger and fear. Iconography and imagery are used symbolically to hint at plot points without giving too much away. Taglines are meant to be cryptic and engaging for audiences.
