Corrected entry: In the scene where Dr. Lesh is explaining what the "light" means to the Freeling boy she calls him Tommy at one point but the character's name is Robbie. It's not that the actress got confused and called the boy by his real first name which is Oliver, so who knows where she got the name Tommy from?
Corrected entry: Watch the scene in the kitchen when the poltergeist puts all the chairs onto the kitchen table. When Diana walks over to the cupboard you can see the reflection of the crew in the kettle moving the set into position.
Corrected entry: Instead of Steve and the neighbor spending all that time fighting with the remote controls and nobody getting to watch their program, wouldn't it just be easier for them to get up and change the channel on the TV? I mean, I know people can be lazy with their remote controls, but come on...
Corrected entry: Near the end of the movie, when Diane falls down the stairs and runs towards the door, she grabs the door knob. When she gets thrown backwards, you can see the cable that is attached to her shirt, pulling her back, in the first couple of frames in slo-mo.
