Factual error: While spinning around dragging Link by the dragon's tail, the dragon blows fire at him and burns his feet, barely. But the way the dragon is spinning, there is no way the fire could have curved that way to get Link's feet. And the fire is also coming at Link's feet from above his head towards his feet, but where the dragon's head is it should be coming from below his feet.
Factual error: After the rug falls over Ganon and covers him, Link blasts a hole in the floor under the evil wizard and he falls through with the rug still draped over him. As he falls in the next shot down a long ways, the rug stays draped over him, completely unaffected by wind.
Factual error: After Ganon captures King Harkinian, he takes him to a circular room and says that Link and Zelda have one hour to surrender the Kingdom of Hyrule and the Triforce of Wisdom or the King will fall a very long time. After he says this, a bright light shines up from the center of the room and begins expanding, it being a hole. However, it is expanding WAY too fast to take an hour to make the King fall to his doom. At the rate of expansion, it would be to the edge of the room in probably just over a minute if not less.
Factual error: Link is next to a flower pot after he rolls off the dragon. The shadow effects on the items around him are all wrong. By the lighting, you can tell that the light source of the sun is behind Link and to the left of the flower pot. The flower pot's shadow is stretching to the right of the screen. But the steps, which are in the same lighting, have their shadows cast to the left, into the light.
Factual error: Zelda gives Prince Facade a compliment when he meets her father. Facade smiles and then looks over, the camera follows his view to a mirror on the wall. It then cuts to the mirror showing his reflection as he winks at himself. The problem is though, when the camera was panning from his position, it showed the mirror was against the wall a good distance from him, as well as facing almost a 90 degree angle away from him. So not only was his reflection too big for his distance, but the mirror would not have reflected his image back to him at that angle.
