Audio problem: At the cemetery, as Harry lies on the ground, when Voldemort leans over him and says, "If they speak of you they'll speak only of how you begged for death," in the shot facing Harry, before Voldemort continues to speak, his mouth still moves, though nothing is heard. (01:27:25)
Visible crew/equipment: In the dining hall when Dumbledore says, "Eternal glory, that's what awaits," it cuts to Harry and the other kids sitting at the table. Right behind Harry's seat you can see a white tape marker on the floor. (00:19:15)
Continuity mistake: Whilst Harry is in the bathtub in the Prefects' bathroom, the foamy bubbles on his face and body noticeably differ between consecutive shots, or disappear then reappear depending on camera angle, particularly when Myrtle is being "attentive" to him. This is not due to his moving the bubbles about. (01:23:45)
Continuity mistake: In the Prefects' bathroom when Harry is in the bathtub, just before Harry touches the golden egg and then when he puts his hand on it, both the egg's and his hand's positions differ between shots. (01:23:50)
Continuity mistake: 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 mistake: In the Triwizard champions' tent, Rita's photographer captures the moving photograph of Hermione and Harry hugging, and subsequently letting go of each other. Later, when Hermione reads from The Daily Prophet, just before Ron opens his package, in the close-up of the newspaper their hug, the release, and where they both stand are entirely different in the moving photograph. (00:54:50 - 01:05:20)
Revealing mistake: In the dining hall, when Dumbledore speaks to the students about the Triwizard Tournament, Hagrid is prominently seen in the background, but it's clearly not Robbie Coltrane in some of these shots and in other scenes throughout the film.
Continuity mistake: In the Great Hall, when Ron takes the dress robe out of the box, there is a plate beside Hermione which has two utensils on its left side and one utensil on its right. However, when Harry says, "It does match your eyes," and in another following shot, there is only one utensil on the plate's left side - the knife is now on the other side. (01:06:00)
Continuity mistake: When the students are dancing to The Weird Sisters at the Yule Ball, Viktor Krum can be seen at the back of the group, jumping up and down, with Crabbe/Goyle jumping up and down behind him with his hands on Krum's shoulders. Immediately after, however, Krum is seen dancing with Hermione, and Crabbe/Goyle has disappeared, with no time to move between shots. (01:16:20)
Audio problem: In the scene right before the champions enter the maze, Cedric Diggory hugs his father, Amos. When they pull away, Amos says, "That's my boy," but his lips aren't moving.
Revealing mistake: On the train to school, when HRH are in their cabin, among the different angles that are presented during this scene are the shots in which the camera either faces the large cabin window or the aisle window, directly opposite it. It is not what is seen that is the problem, it is what we don't see. When the camera faces the large cabin window we should see the scenic reflection of the window opposite it, as the train speeds along (and vice versa the aisle window), but we don't. What we do see reflected is the light colored wall beneath the blacked out window. The camera filming the shots from this angle is positioned at that window and in order not to see the outline of the camera/crew, the window was covered.
Visible crew/equipment: In a number of shots within various scenes, the reflections of the reflector screen and set lights are briefly visible in the lenses of characters' glasses, such as Rita Skeeter's, or in characters' eyes.
Revealing mistake: When Dumbledore, Barty Crouch, and the rest are in the Triwizard champions' tent, as Madame Maxime stands behind Fleur with her hands on Fleur's shoulders, in Fleur's close-up it is rather apparent that they are not Madam Maxine's hands.
Continuity mistake: In the dorm, after Ron moans, "Yeah, that's me, Harry Potter's stupid friend" as Harry leaves his bed and walks to Ron, there is a single rectangular window beside his bed and another window about a foot above it. Later, after the Yule Ball, in the exterior zoom-in shot the crow flies toward the side-by-side double window, arched at the top, as it heads for the window sill, and in the next interior shot, the crow lands on the sill as Harry sleeps beside that window. (00:38:30 - 01:22:30)
Continuity mistake: When Dumbledore reveals the Triwizard Champions, in some shots one of the Weasley twins sits beside Harry and Seamus near the wall, along with Hermione, Ron, and Neville. In other following shots, both Fred and George are sitting together on the opposite side of the table.
Continuity mistake: There is a scene where Harry is holding the letter from Sirius and we can hear Sirius's voice reading the letter. The words on the letter are different from the words we hear Sirius reading. Particularly the end where Sirius says, "P.S. The bird bites" the letter says, "By the way, the bird bites."
Continuity mistake: When Rita grabs Harry to interview him, in the next shot, as the Quick-Quotes Quill springs up, the paint can, brushes, etc are on the steps. Their positions change in the Quill's first close-up, as it writes in the notebook. (00:39:55)
Continuity mistake: 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 mistake: In the dining hall, when Hermione begins reading Rita Skeeter's article mentioning the Hungarian bon-bon, the newspaper and Hermione's fingers change position between the semi close-up and close-up.
Continuity mistake: In the Great Hall, when Harry dribbles on himself, the plate to Hermione's right (as she holds The Daily Prophet up) has food and utensils lying on it. However, in the following shots, there is only an empty plate with utensils set on both sides, beside Hermione. (01:05:00)
Answer: Voldemort's spell undid the Sacrificial Protection that Lily bestowed on Harry, but the Bond of Blood is a separate protection bestowed if the person sacrificing their lives is a relative. THAT spell is still renewed as long as Harry keeps returning to the Dursleys until age seventeen. Voldemort has removed one protection, but a second is still in place.
