The trailer uses a variety of techniques to establish suspense and fright. It begins with a sudden loud bang to grab the audience's attention. Throughout, it alternates between showing the father resisting the supernatural force controlling his mind and showing the force growing in power. Close-ups, zooms, and fast cuts between shots build tension. Low-key lighting surrounds characters in darkness to suggest the evil force is lurking nearby. The force is presented as a ghostly, aggressive female contrasted against the modern family. Its growing dominance over the frightened family is the central conflict teased in the brief trailer.
