The document discusses the effectiveness of combining a main product (a short social realist film about gang culture) with ancillary texts (a film poster and film review). To create the ancillary texts, the author analyzed other similar film posters and reviews to identify conventions. The film poster design incorporates elements found in other posters like the main characters, quotes, and credits. The film review follows conventions like using action shots and a column format. All three products - the film, poster, and review - are closely linked to promote the film to their target audience and provide context, analysis and motivation for viewing.
