Corrected entry: In the scene where the three kids are playing hide and go seek, the lights are thrown off by the main switch. However, when they run into one of the rooms there is a digital clock displaying the time.
Corrected entry: In the cliff scene, Susan says, "Hold on Edward!" Her son's name is Henry and her nephew's name is Mark. (01:20:00)
Corrected entry: At the end, when Mark is locked in the room, he doesn't have his jacket on. After he breaks the glass and his uncle and the doctor run in he's in such a hurry to run out of the house before they get him. When we see Mark outside he has his jacket on. There was no way he could have had time to stop, get his jacket, and put it on.
