The document analyzes codes and conventions that are commonly used in horror films. It discusses key elements that should be included in a horror film opening, such as: isolating the location in an area like a house or woods; using non-diegetic music and diegetic sounds like rain or breathing to build tension; employing low key lighting to create an ominous atmosphere; and utilizing camera shots like close-ups and high angles that make characters seem small and vulnerable. It also notes the narrative should follow stereotypical situations seen in other horror film analyses, such as featuring a young female protagonist in danger from an intimidating male antagonist, while stock characters like friends try to help but are injured.
