The document analyzes and summarizes 15 different opening title sequences from horror films. It observes that most OTS are symbolic and use techniques like asynchronous sound, narrative enigmas through headings, and mise-en-scene to represent characters. Specific films highlighted include The Walking Dead, which uses a dark color palette and abandoned locations to set an ominous tone without characters, and Evil Dead, which has a nonlinear sequence showing blood spreading to foreshadow violence in a gory yet unconventional way using opera music. The document discusses how opening sequences prepare audiences for films through setting atmosphere, mood, and leaving questions unanswered to generate interest.
