After Mark and Fitzhugh yell out when the drainage plans roll up, they were by the front stage-left corner in the close-up shots, but on the wider shot with the giants they are not there.
When the giants are shown lowering the spoons the ropes used are the same thickness as the ropes that were used to lower Steve and Dan but when seen from Steve and Dan's perspective the spoons are on a thinner cord then the ropes they are on.
When Dan steps on a root branch that breaks away, the plastic or metal strap that held it is clearly visible as the branch dangles.
The vertical and horizontal shafts and the area where the children are are well lighted.
At about 16 the minute mark, the brand name "Dodge" is visible on the side of the fire/rescue truck.
