When Kathy is talking to Sarah in the store, (with the camera behind her) her mouth movements don't match her speech pattern.
When the 3 boys are knocked off their bikes by the hosepipe the bikes disappear immediately afterwards.
Errors in geography
The story takes place in New York state, but in the final scenes with Christmas decorations everywhere, it is obviously still summer.
The end of the movie takes place during Christmas season yet all the trees are fully green.
The few times we see Sarah driving, when seen from this perspective of outside the windshield the gear shift lever can be seen in the park position.
