Deliberate mistake: In the opening, the kids are looking up at the floor boards. Uniform light seeps through, but as it turns out, the house was small and swarming with an angry mob carrying torch. The light is not really compatible with that scenario, and in fact when the scene is shown later again, the lights are warmer and you can see the torches flickering. It's most likely a trick not to give away exactly what was hunting the kids in the basement. (00:01:00 - 01:11:20)
