Revealing mistake: In the Forbidden Forest, HRH are introduced to Grawp. Just as the giant lifts Hermione off the ground, in the shot from behind her, Hermione's legs disappear below her calves; the digital lines are actually visible. Slow-mo is not necessary. (Only visible on fullscreen DVD.) (01:29:40)
Continuity mistake: When Dave leaves his house for work, there is a skateboard leaning up against the wall by the door and there is an umbrella stand with a lot of umbrellas in it.

Additionally, during this scene, all the other writing on the blackboard changes between shots as well. (00:06:15)
Continuity mistake: When Lyra is walking through the palace to meet King Ragnar of the Ice Bears, there are a great many bears all around her, with a few following her right up to the king. She gets to the king, and when the shot pans out to the hall, suddenly all the other bears are gone. Even if they all left the hall, it would take more than a second or two to do so.
Continuity mistake: At the mass hanging, when the singing begins, in one shot of the people (with the boy) standing at the gallows, the others down below, who wait at the head of the line, are also seen behind them singing. In a following shot, some at the head of the line differ.
