Character mistake: Early in the film, Sister Paxton reveals that she wants to come back as a butterfly after she dies. Reincarnation is not a tenet of Mormonism.
Factual error: Whilst trapped in the basement, the two sisters pull a rug towards them to obtain some matches, then take them downstairs and light them by striking them on a rough surface. The matchbox is labelled 'safety matches' so they would not light without using the striker pad on the box. (01:12:00 - 01:14:00)
