The poster depicts the two main protagonists, detectives David and William Somerset, standing back to back with semi-transparent images. Their serious expressions leave their roles ambiguous. Between them are listed the seven deadly sins that are central to the film's plot. The rusty orange and red color scheme suggests danger. The bold white font draws attention to the film title and actors' names. The tagline references the biblical story of the seven sins and hints at the detectives' efforts to save seven people.
