Continuity mistake: Dumbledore wears a thin silver strand, with dangling silver balls, tied round his beard throughout the film, and the position of this strand differs in consecutive shots, depending on the camera angle. For example, when Dumbledore stands beside the pensieve, whilst speaking with Snape, McGonagall and Moody.Super Grover
Continuity mistake: During the first part of the movie, Moody doesn't have a eyebrow over his Magic Eye, it is clear because you can see the stitch marks. Then when he is talking to Harry he has a bushy white eyebrow where there wasn't one before. (00:25:20)
Continuity mistake: Just before Moody turns Draco into a ferret Harry has a confrontation with him and pushes him. In the first shot right before Harry pushes him they are almost face to face. Cut to behind Harry after he pushes him and Draco has been pushed back several feet. Cut to behind Draco just as Harry says 'he's vile and cruel' and they are now almost face to face again. (00:48:40)
Continuity mistake: When Mr. Weasley, HRH, and the rest reach the boot Portkey, to take them to the Quidditch World Cup, in the first close-up of the boot (with the sky behind it) there are many very tall blades of grass on the mound around it. In the next shot, just as they start to encircle the Portkey there are much less single tall blades - before anyone has had a chance to stomp on them.Super Grover
Continuity mistake: After the 3rd task, as Moody is taking Harry back into the school, the camera cuts back to the students. Neville stands to the left (viewer's right) of Viktor Krum and the Bulgarians. In the next shot Neville stands to the left (viewer's right) of a girl, who is seen in the next shot standing beside Ron, Hermione and other students (not the Bulgarians); Neville is out of place during these shots.
Continuity mistake: In the Gryffindor common room, after Ron heads up to the dorm, Harry realizes Sirius has gone. In the close-up of the Daily Prophet, the unwrinkled headline "Teenage Tragedy" is displayed prominently as the newspaper burns up, whereas in the previous shot (before Harry's close-up) the "Teenage" part of the headline is unseen.
