Visible crew/equipment: When the boy takes the boat out for a ride by himself and is riding it around in circles, you can clearly see the helicopter's shadow in the center of the circle.

Continuity: Watch kid drive Norman's power boat. He is at the steering wheel, and appears at the left and right side of the boat in the same scene.

Visible crew/equipment: In the last scene, as the camera pulls away, the helicopter's shadow is visible on the surface of the lake.

Revealing: When Norman and Billy crash the boat, the side panel rips off of it before they hit the rock.

Continuity: When the boy is dropped off at the cabin, Ethel's sweater is zipped down. It goes to a close-up of her and the zipper is up. In the next shot, the zipper is down again.

Continuity: When Norman is helping his wife uncover the furniture in the summer cabin, she hands him some sloppily rolled up sheets that drag the floor. The camera never leaves them, but for a few moments it zooms in and you don't see below their waists. When the camera zooms out again, the sheets in Norman's arms are all neatly rolled up.
