Continuity: At the end, the wound on Harry's left cheek changes from a series of small scratches when he says good-bye to Dumbledore to a deeper more singular wound when he says good-bye to Ron and Hermione.

Continuity: After Draco is changed back into a boy (from a ferret), Moody sticks his staff into the ground before he chases Draco around the tree. Initially his staff is leaning at a 45° angle, but when Draco comes around the tree and leaves the courtyard the staff is standing upright, at a 90° angle.

Continuity: During the Priori Incantatem, Harry is shown using both hands to hold his wand steady. The very next shot, however, shows him holding with just one hand, then his other hand comes up to grasp the wand as well.

Continuity: Straight after the second task Hermione wraps her own white towel round Harry, but between shots it jumps back to her shoulders, then back to Harry's several times.

Continuity: When Fred or George passes the note to Ron in the Great Hall, encouraging him get a date before all the good ones are gone, the position and style of writing on the note changes between shots. The number of lines changes from four to three and the words are written lower on the paper when Ron reads it.

Revealing: Aboard the Hogwarts Express, when Harry stands beside the open window and sends Hedwig off with the letter for Sirius, surely his hair and clothes would be wildly moving about, because of the strong wind from the fast moving train.

Continuity: When Harry opens the letter from Sirius Black, he throws away the string that was tied around the letter. When it cuts, the string is back in his hand.

Continuity: During the second task, just as Krum and Hermione pop up from underwater and Krum's sharkhead disappears, in this specific shot Fleur (NOT another Beauxbaton student) stands on the platform in the background and her hair is fairly dry, blowing a bit in the wind. However, in a following close-up, Fleur's hair is soaked and stringy.

Continuity: When Harry is on the Hogwarts Express, it is apparent that his scar is missing or very much out of place. Then during the second task, when Harry is swimming, the same thing happens.

Continuity: At the first challenge, just before the Horntail makes its appearance, there is a tight close-up of the egg as Harry stands in the stone "doorway" in the background, on the left. Clearly it is not Daniel Radcliffe, but his stand-in (his face differs and he has a shorter, bowl-type haircut) who is standing there, for this one specific shot.

Continuity: When Fred and George pass Ron the note in the Great Hall encouraging him get a date before all the good ones are gone, the writing is on the top of the page. When Ron reads the note, it appears that the writing is a bit lower on the sheet of paper.

Continuity: When Harry's name has just come out of the Goblet, we see a shot of Hermione with Ron in the background. In this shot, Ron is looking up at Hermione. A second later from a different angle, Ron is looking down, then moves his head to glare in Harry's direction. Nobody can move that fast.

Audio problem: When the Goblet of Fire is about to reveal who the three champions are the clock strikes 9. But if you listen carefully while Dumbledore is talking it only rings 8 times.

Continuity: When Ron glares at Harry in the Great Hall, he is angry with him for getting his name into the Goblet, but his face has dramatically changed from the previous shot (where he is in the background, behind Hermione).

Continuity: When Hermione is walking over to wake up Ron she places a candle on the table. When it cuts the candle has moved closer to the edge of the table.

Continuity: When Hagrid stabs Professor Flitwick in the hand with his fork, the fork changes places slightly between the wide shot of them and the close-up of Flitwick's hand, even though the fork hadn't been removed yet.

Continuity: Right before the third task, Igor Karkaroff puts his hands on Krum's shoulders. In the next shot, however, his hands are off his shoulders and he is standing a respectable distance away. This change continues throughout the rest of the scene.

Continuity: After Cedric Diggory is killed in the cemetery, his body changes position during the scene, particularly its proximity to the Riddle monument.

Continuity: When Ron enters the common room, Harry places himself at the edge of the couch. When it cuts, he has moved further in on it.

Continuity: When Fred or George says "Sounds like the Irish has got their pride on", right before Arthur enter the tent, we see him swinging a pillow to his right ready to hit. When it cuts to Arthur entering, he has his pillow to his left.
