‘Harry Potter and the Prisoner of Azkaban’ Mistakes You’ll Never Be Able to Unsee

Following the frightening encounter with the Dementor on the train, Lupin gives Harry a chocolate bar. If you watch closely, you’ll notice a continuity error: the chocolate bar seems to change size between shots. Sometimes it looks almost full, and then suddenly much shorter, as if someone took a bite. The wrapper also shifts position. Keen viewers can spot the prop being reset to a larger piece several times during the scene.
