The poster uses dull colors like black and grey to create an ominous and unsettling atmosphere. Symbols like an isolated house and a faded child's face in the background are intentionally cryptic. The central female figure appears insecure and is meant to draw the audience's attention. Quotes from critics and mentions of starring actors are intended to increase interest in the film. The tagline "All the children are gone, except one" leaves viewers with unanswered questions in a way that makes them want to learn more by seeing the film.
