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?

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.
