Continuity mistake: When Dumbledore first introduces Lupin as the new Defence Against the Dark Arts teacher, the camera pans to the Gryffindor table. You can see that Ron and Hermione are sitting opposite each other with their dinner sets in front of them. Then Malfoy insults Harry, then when it cuts to Ron saying "Shove off Malfoy" Ron is now sitting opposite the girl who was beside Hermione and not Hermione herself, and the girl couldn't have just moved across because all of her dinner set is in front of her too, perfectly set out.
