The document discusses different strategies for film posters to appeal to mainstream versus independent film audiences. For mainstream films, posters include recognizable cast names and images to attract viewers and be marketable. For independent films, posters may feature producers/directors' names, focus on the title in large text, and use ambiguous focal images that don't give away the plot in order to intrigue audiences and gain more awareness through word of mouth. The goal of both types of posters is to get viewers to watch and enjoy the film thoroughly.
