Just after the second task, Hermione wraps her white towel around Harry's shoulders.
However, in the next couple of shots, the aforementioned white towel switches between her shoulders and Harry's.
When Harry and Cedric are first transported to the cemetery, the cup lands on a grassy field, far from the Riddle monument.
However, in a later scene, it's right beside the Riddle monument.
There's a scene in the movie where Mad-Eye Moody is writing his name, as well as the unforgivable curses on the chalkboard.
However, his handwriting changes in between the shots.
During the scene on the Hogwarts express, when Harry uses Hedwig to send a letter to Sirius, he sends her out the window... yet his hair isn't blowing.
Shouldn't it? He is on a fast-moving train, after all.
At the end of the movie, Harry gets this scratch on his face. Or was it one scratch?
When he's saying bye to Dumbledore, it's a couple. When he says bye to Ron and Hermione, it's one long gash.
At first during the Priori Incantatem, Harry uses both of his hands to keep his wand steady.
However, in the next shot, he's seen holding his wand with one hand.
After he says the line "If they speak of you they'll speak only of how you begged for death," while Harry is on the ground, it cuts to Voldemort.
His mouth is moving, but nothing is heard.
There's a moment in the dining hall where Dumbledore says: "Eternal glory, that's what awaits!"
At this moment, if you look closely, you can see a piece of masking tape on the floor for the marker.
At the moment where Harry is captured by the statue in the cemetery scene, Voldemort raises his arm to Harry's head and says "I can touch you now" to the captured boy.
A couple of cuts later, his sleeve is back up around his elbow.
He didn't even stop to move it! Yet another flimsy mistake in the movie (but not the worst, for sure).
When Harry is in the bathtub of the prefect's washroom, the bubbles on his face change depending on the shot.
This isn't because he's moving around or anything, either. This is just a flimsy mistake.
When Harry opens the letter from Sirius Black, at first he carelessly tosses away the string that was holding it together.
However, in the next cut, the string is in on his lap.
In the dining hall, when Dumbledore is talking to the students about the Triwizard Tournament, Hagrid is standing the background.
Except it's obviously not the Hagrid we know, but rather his actor's double.
This is during the scene where Ron takes the dress out of the box. In the first shot, there are two utensils on the right side and one on the left.
In the next shot, they've switched.
