Visible crew/equipment: When E. Buzz is heading for Dana's door, someone wearing blue jeans and a red shirt can be seen briefly in the doorway. (00:02:02)
Continuity mistake: The piece of licorice that Carol Anne puts into the cigar box with the dead parakeet "for when he's hungry" appears to be close to 6 inches long when she's placing it in the box but no more than a couple of inches long when it's shown in the box a few moments later. (00:10:10)
Revealing mistake: When the father tucks Robbie in and Robbie says "I don't like the tree, dad." the camera shot begins rolling to the left. Robbie flinches when reacting to someone telling him to lean back more so he's not blocking too much of the father's face. The father also improvs a solution by gently pushing Robbie's shoulder back a bit as well. (00:18:55)
Revealing mistake: When the chair moves across the kitchen floor, Craig T. Nelson goes to investigate it (after it has stopped moving). He goes up to the chair and flips it over. If you look closely, Craig almost hits the camera with the chair's legs. You can tell this has happened because the camera moves up very quickly and Craig looks straight at the camera crew with very big guilty eyes. This is more easily visible on the widescreen version of the film. (00:33:30)
Continuity mistake: Just before the house starts to implode, Teague is backing away from it and as he does so, he passes a couple of white garbage bags on the sidewalk and backs into the street. In the next shot, taken from across the street showing bystanders being blown backwards, Teague is visible in the background; he's back on the sidewalk tripping backwards over the same bags he safely passed moments before. (01:48:10)
Continuity mistake: At the start of the film, the dog is seen going from room to room looking for food. Just before he goes into Dana's room, someone can be seen through the crack in the door, moving from left to right.
Continuity mistake: When Carol Anne is being sucked into the closet vortex she clearly lets go of the white wicker headboard of her bed. In the next shot, the child (actually a dummy or a stunt double) is seen sailing into the closet, grasping a sizeable section of the now broken headboard.
Visible crew/equipment: In the breakfast scene when Robbie's milk glass spontaneously shatters from the bottom. Watch closely, you can see a string coming out of his cereal bowl and attaching to the bottom of his glass. Robbie just needs to give the glass a little tug, and splash.
Visible crew/equipment: Near the end of the film, when she lands behind the stairs. If you look in the right hand corner, underneath the stairs, you can see tennis shoes running by.
Continuity mistake: The wicker headboard of Carol Anne's bed is ripped apart when she holds onto it to try to keep from flying into the closet. Towards the end of the movie, when her mom tucks her into bed, the headboard is intact and has had no repairs.
Continuity mistake: A few seconds after Steve stops the car for his daughter, Robbie yells. During this brief scene you can see a bluish flannel on Robbie. About eight seconds later, Robbie's red pajamas reappear. Previous to these scenes, Robbie was wearing his red pajamas.
Continuity mistake: When the men are watching football, they are reacting as if they are watching live action. However, the images shown on the TV are clearly in slo-motion.
