The poster aims to entice viewers to watch the film by making the antagonist Rebecca seem like an ordinary girl while hinting at her true psychopathic nature. It uses direct eye contact and faded focus on her face to make her appear powerful and threatening. The layout places the image in the center with framing text, and contrasts a dark, gloomy background above with a brighter area around her image, representing her mysterious characteristics. The color scheme of red and white text connotes danger and emphasizes her power over her roommate, the protagonist.
