Continuity mistake: During the very last scene with all of the Freelings, Taylor and Tangina, right after Taylor leaves alone in the Freelings' car and the Freelings start walking down the street, the camera pans back so you can see the whole neighborhood including where they were just standing. Where did Tangina go?
Continuity mistake: After the father drinks the 'devil' thing in his bottle of wine, he heads to the bathroom where the mother and Carol Anne have just had a bath and hairwash. When the mother realises there's something not right with the father, she sends Carol Anne - with soaking wet hair - out of the bathroom. As the father starts getting aggressive and saying hurtful things about Carol Anne, she comes to the bathroom door looking really upset - and her hair is bone dry.
Continuity mistake: When the family escapes from the garage after the chainsaw has cut up the car and left a huge scratch in the windscreen, we get a front view as they drive and talk. The screen is clear; no scratch.
Continuity mistake: As the Freelings drive to Cuesta Verde, the wagon is awfully quiet, especially after the chainsaw cut through the roof.
Continuity mistake: Look at Robbie's baseball bat when he is sitting on the couch. You can see the positions don't match from one shot to another.
