The document discusses how the author developed a consistent brand identity across three promotional materials - a film poster, trailer, and magazine cover. Specifically, the author used: 1) the same characters represented in the same way, 2) a single recognizable font, 3) similar dark and light colors, and 4) conventional layouts that appeal to the target audience. This consistent representation of themes, fonts, colors and targeting of the audience helps promote the film by clearly linking all the elements together under one identifiable brand.
