The introduction of Halloween uses several techniques to unsettle audiences. It begins with a black screen during the title sequence to build tension without revealing anything. The Jack-o-lantern is a genre signifier that corresponds with traditional horror themes of evil and ghosts. A POV shot from the killer's eyes makes viewers uncomfortable and creates tension. When the killer puts on a mask, it creates mystery as audiences cannot establish what is happening. Frequent long shots reveal more than one thing on screen for audiences to focus on, while a single close-up of a knife seems to glorify this foreshadowed important object.
