Continuity mistake: In the exterior front shots of Elliott's house there are some significant changes to the landscape in different shots. For instance, the two lampposts at the bottom of the driveway change to an entirely different style in some shots, and the huge garden boulders repeatedly vanish and reappear. Also, note when Michael takes off on Elliott's bike to go search for ET, the in-ground lamppost that should be beside the mailbox has vanished, but it reappears when all the government agents are setting things up outside the house.
Continuity mistake: The blood stain on Kirk's jacket keeps moving around.
Visible crew/equipment: After Conan is set free from slavery he finds a cave where he removes a sword. When he climbs out of the cave you'll notice someone's hands near his feet pushing up his shackles. (00:29:25)
Continuity mistake: When the Jun hoard attack the Emirite village, Dar gets knocked unconscious and his dog starts to drag him away. After Maax arrives, the dog is shown dragging Dar away a second time. Two mistakes are apparent. The dog is pulling on the cloth of his left shoulder in this shot. First, when the dog is pulling, the dog stops to get a better grip on the clothing. When the dog lets go of the clothing, Dar keeps sliding even though the dog isn't pulling. Second, when they show the close-up of Dar, the dog is pulling on his right side, not the left. Then again on his left side and again on his right side. It switches a couple of times.
Visible crew/equipment: Thin wires are visible, attached to the crystal bats as they fly off to watch Jen and Kira.
Continuity mistake: The sequence in which Dragon is chasing Mrs. Brisby through the field, up the tree and eventually into the mill's lake, watch his eyes. The original placement is (from viewer's perspective) blue on the right and gold on the left. When he chases her up the tree the gold one is visible on the right, it then switches back when the camera cuts back to a wide shot. This happens again a few seconds later near the lake.
Visible crew/equipment: When Alan and Lora go to see Kevin Flynn at his game room they find him playing his videogame 'Space Paranoids'. After he finishes playing, he turns around to talk with Alan and Lora. As they are speaking you can see the microphone coming up from the bottom of the screen. It even hits Kevin Flynn in the hand.
Factual error: Many palace scenes in the mini-series are set in the Forbidden City. This is incorrect, as the Forbidden City was built under the Ming Dynasty (1368-1644) and not completed until about 1420, almost 100 years after Marco Polo's death.
Continuity mistake: In the scene just before the snowman comes to life, the clock in the hallway reads midnight. But a little later, when he is showing the snowman around the house and he is about to lead him upstairs, the clock reads 8:05.
