This document discusses conventions of film posters. It explains that film posters aim to catch people's eyes with a main image related to the film's genre. Posters usually include the director, producers, and main actors to promote the film. Once a film is screened, posters can be updated to include positive reviews and awards. Taglines are used to emphasize the film's key points and hint at the plot. Dates are included to show when the film will be in theaters or available for purchase. Symbols on the poster can also provide clues about the film's plot and themes.
