Continuity mistake: Likewise, 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.
Continuity mistake: When the dog jumps in the back of the cab, he gets in the right side and Robbie is nowhere to be seen. It cuts away very briefly, and when it cuts back suddenly Robbie is very much on the right side of the seat and the dog is on the left- not enough time for them to have moved and settled in.
Continuity mistake: Right after JoBeth Williams and Craig T Nelson joke with Dr. Lesh about not showing the tapes of their haunting on "60 Minutes" or "That's Incredible", JoBeth walks to the table with Dr. Lesh's flask in her hand. As she walks from the sink, there's a silver cap on it. When she gets to the table, the cap is gone. She couldn't have removed it out of sight, she had a coffee cup in her other hand.
