The document discusses the conventions used in creating a horror film trailer and related marketing materials. It begins by outlining research conducted into existing horror trailers to understand necessary elements. Key conventions followed include using footage from an in-production film to promote it, focusing on protagonists, locations, sounds, and introducing main characters. The trailer challenges conventions by not having a satisfying conclusion or the typical "good over evil" narrative. Related materials like a magazine cover and film poster were also created, following researched conventions for those media.
