The document discusses the effectiveness of combining a film with ancillary texts like a poster and radio trailer to promote the film. It explains that the film, poster, and radio trailer all have a strong military theme to connect them. A tagline of "One man must stand alone to face his fears" is used in all three to further link them. Specific design elements were chosen for the poster and sounds were selected for the radio trailer to reference elements in the film and create consistency across the promotional materials. The combination of the poster and radio trailer was deemed effective at promoting the film by reaching a wider audience than either could alone.
