The document discusses genre conventions of disaster movie trailers. It explains that the 1972 film "The Poseidon Adventure" established the disaster movie genre by depicting a simple series of events leading to an eventual catastrophe. This includes setting the scene, providing background information, showing the disaster unfold, focusing on a small group's survival, and creating suspense around whether characters will live or die. Additionally, disaster movie trailers often link the major event to characters' personal stories. Stock character stereotypes are also commonly used that audiences can relate to, with one or two being killed off to increase intensity.
