The teaser trailer is typically 1 minute or less in length to pack the trailer with intense action and intrigue audiences. Fast-paced editing with quick cuts is used to magnify the action and build suspense. Narrative and lively music are used to provide context and drama while concealing much of the actual plot. Shots of violence depict the protagonist engaging in zombie-like behavior of eating human flesh and attacking others to set the scene of the supernatural horror genre and give a sense of the conflict without revealing too much of the story. The title is shown at the very end to leave audiences wanting more information and anticipating the full trailer and film.
