Goofs

When Caroline is giving Ben his bath, she drops both the soap and sponge into the bathtub water. When she comes back to the bathtub, the soap is still floating in the water, but the sponge has appeared on the rack over the tub.

When Ben is trying to kill himself, Caroline isn't as wet when she goes to wake up Violet, but is completely wet when she first goes outside to help Ben.

When Caroline first finds the door in the attic, there's a flowery pattern on it. When she goes back to unlock it later, it's not the same doorknob.

When Caroline is reporting for her interview, she steps out of her car and walks up to the house for the first time. We see her back from the car's side mirror. In reality, the car is parked (and she walked) in a direction that would not allow her to be visible in the car's side mirror.

When Caroline crashes into the gate with the Volkswagen, the front bumper falls off. It disappears and reappears between shots.

When Caroline first gets to the house, she exits her car and starts walking towards the front door. Her reflection in the car's mirror would only show her back like that if she were walking towards the back of the car, rather than at right angles to the car.

When Caroline makes a 911 call, she gives the street address of the house and says it's "in Terrebone Parish." Parishes are like counties in that they are composed of many, many different small towns and cities. She would have to give a specific city/town name in order for emergency vehicles to get there. However, because the house isn't located in any particular town (but rather out in the swampland), it is more likely that the address given to 911 by Caroline IS the full address, and that what is supposed to be a street name is actually just a name of a very scarcely settled small town with no particular streets. Thus, an address consisting of just a town name and house number would be legitimate.

In the beginning of the movie a man is supposed to be dead but you can still see him breathing.

When Caroline finds the mirrors in the attic, another person's reflection is behind her.

After Caroline decides not to throw her patient's belongings in the trash container, the lid is lifted up (by an off screen crew member) before she grabs it in order to close it.

Violet rides up in the elevator when all power is out.

Caroline needs chalk to make a protective hoodoo symbol. She uses blackboard chalk, but that is made of gypsum, not of calcite.
