Visible crew/equipment: Before the slug crawls out of the room, the crew member shaking the bed is noticeable on the left side of the screen. (01:07:25)
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?
Revealing mistake: It is obvious a dummy was used when Steve is thrown from his easy chair into the kitchen cabinet.
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.

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.
Continuity mistake: When the leak falls on the toy phone there's a close-up of Carol Ann's feet surrounded by a bunch of toys. When the angle changes half of the toys are gone.
Continuity mistake: During the leak scene, the toy phone cord swaps from being shaped like a number 8, to shaped like a loop between the first and second shot.
Other mistake: Taylor parks his car in Cuesta Verde, next to a couple of crates next to the pilot's door. He steps down and walks straight without looking down, which is impossible for he should have tripped.
Continuity mistake: After the slug grins at the parents, his face becomes slimier and with two long dripping bits of slime by his mouth.
Continuity mistake: When the movie starts and both Indians sit by the bonfire, the old one holds the drum-stick at face level or waist-level, depending on the angle.
