The document discusses the effectiveness of combining a film's main product (trailer) with ancillary texts (poster and magazine cover) for promotional purposes. It analyzes a marketing campaign called "Changeling" as inspiration. For their own campaign, they feature the protagonist Sophie Baker prominently across all products to create a strong, recognizable brand. Key elements like the title, tagline ("I will find her") and font are also consistent. Conventionally, the poster and magazine cover feature close-up images of Sophie with tense facial expressions to suit the genre and attract the target audience while differentiating the products from other films.
