When Michael Baldwin and Ed first meet, Michael walks in to meet Ed who is standing on his couch. Ed hopped off the couch to speak with Ed and has his hands behind his back. On the reverse angle shot Ed is standing with his hands in front of him.

The name of the movie is "The Night They Saved Christmas," but when Michael terminated the dynamite countdown that saved North Pole City and Christmas, it was daytime, not nighttime.

The fact this movie takes place up by the North Pole during the beginning of winter, there should be 24-hour darkness, but there's day and night in this movie.

Santa explains time zones with "When it's midnight in New York, it's only five o'clock in the morning in London." London is five hours ahead of New York, so it's properly "already" five o'clock in the morning.

When Ed is taking them to North Pole City in the tracked vehicle, the tracks of the camera vehicle can be seen in the snow in one wide shot of the tracked vehicle traveling forward through the snow.
