When casting actors for their film, the filmmakers considered the demographics of their target audience, who were under 35, and cast actors of a similar social class. This included casting a 16-year-old to play the mother and a 5-year-old to play her child. Throughout the film opening, they use conventions like low-key lighting and a slow editing pace to attract audiences to the genre of psychological horror. They also included a role reversal with strong female characters and no male figures to appeal to audiences who wanted to see this. The plot of a child going missing in an abandoned house engages audiences through mystery while differing from other films through its lack of male characters.
