Continuity mistake: There are only 2 kids in the child's bedroom, but when you see the TV commercial they are watching early in the movie, you see FOUR children reflected in the screen. Way to the left is a boy dressed in white or light blue, leaning over a boy in dark blue to the right, then next is Dylan or Cole Sprouce (actor), and the other child actor, dressed in white. (00:04:50)
Suggested correction: I agree that the quite blurred reflection does not match what could be expected, but I do not agree the reflection is showing two other kids in the room with Bobby and Justin. To the right, it looks like there is a very inaccurate reflection of Bobby and Justin. To the left, there appear to be images of what they are seeing on the TV.
