This document discusses types of signs used in film posters and their meanings. It provides examples of iconic, symbolic, and indexical signs. Film posters use signs like costumes, lighting, colors, and body language to convey messages and hint at the genre and plot. Effective posters deconstructed in the document use faint facial images and placement in the sky to indicate a spirit or death, and establish settings and postures and scales to imply searching and difficulty in finding someone. Color balancing and bold titles also help audiences quickly understand the genre and title.
