The document evaluates the effectiveness of combining a main product (a short romantic comedy film titled "Rendezvous") with ancillary texts (a film poster and radio trailer). It finds that researching film posters and radio trailers helped ensure the ancillary texts accurately captured and advertised the main product. The film poster and radio trailer were both effective because they coincided well with the short film through elements like matching iconography, quotes, sounds, and music. Overall, the combination of the main product with ancillary texts that were carefully designed to synergize with it created a successful promotional package.
