The document discusses initial ideas for a horror film opening sequence by analyzing openings from Scream, Saw, and Jeepers Creepers. The author chose the horror genre because there are many existing openings to learn from and it allows for creative planning and filming. Specifically, the author likes how Scream uses a scream sound effect during its title, Saw films the floor with blood and equipment before revealing its title, and Jeepers Creepers provides credits in a horror-appropriate font with ominous music and foreshadowing dialogue.
