Visible crew/equipment: When the two boys are in front of the Grinch's front door, a big monster comes out of the front door, scaring them. The boys then jump off the side of the rocks, and a cable attached to them is perfectly visible.
Suggested correction: I've watched this scene over and over, and there is no cable visible as they jump.
Visible crew/equipment: During the Basketball wish, while Elliot is being interviewed by the sportscaster, you can obviously see cardboard "people" filling the stands in the background. (00:49:45)
Visible crew/equipment: Sometimes, especially at night, you can see the lights of the equipment reflect off of Tony's glasses. We know this isn't the moon or a car light because for one thing it's the wrong shape and when Rudolf is sucking blood out of the cow there is no moon or car nearby. So there is only one place the light could have come from, and that would be the crew equipment.

Visible crew/equipment: In the church scene, when the priest stops dancing on the pizza and the camera goes up you can see in the left middle of the screen a camera just poking out as when the priest talks it goes right to him. (00:20:20)
