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: At the beginning of the movie when Taylor goes down into the hole where the house was he wades through water almost up to his neck. When he returns to the ladder, his shirt is only damp in spots and only slightly above the waist. His jeans do not appear wet at all.
