The document discusses film poster conventions for different genres. Horror posters typically depict evil, pain/suffering, abnormal people or gore. Thriller posters often reveal the victim but not the villain. Drama posters can show peaceful backgrounds or hint at the story. Comedy posters usually feature something strange and place the main character centrally. Posters are intended to attract audiences without revealing too much of the plot. They prioritize including the film title, actor names and production credits.
