Factual error: In the scene where Caroline finds the conjure record, it is written in ink on the sleeve that it is from "New Iberia Parish". Such a parish does not exist in Louisiana. There is a town called New Iberia, but the parish for that town is Iberia Parish.
When Luke brings Caroline back to the house after knocking her out, Violet demands to know where Ben is. In this shot her tears are black because of the mascara, but in the next shot all her blackened tears have disappeared.
