Corrected entry: In the scene near the end of the film where Harry tricks Lucius Malfoy into freeing Dobby, Malfoy is understandably enraged. He pulls out his wand and snarls "You've lost me my servant, boy." and then begins to shout "Avada....." before Dobby interrupts with "You shall not harm Harry Potter." Readers of the books will recognize this as the first word of "Avada Kedavra", the Unforgivable Curse which results in the instant death of the victim. An interesting way to show just how angry Malfoy was. It was also quite reckless. If anyone found out he did it, he would spend the rest of his life in Azkaban (until Harry Potter and the Order of the Pheonix anyway) if it was ever discovered he did it. And of course Dobby would have been a witness, unless Lucius killed him too. DVD subtitles actually show that he is starting to say "Vera-", but that doesn't match his mouth movements.
Corrected entry: In Harry's room, there is a stool. When he talks to Dobby, the leather is blue. When Dobby goes to sit on it, it is black.
Correction: The reason the leather on the stool seems black when Dobby sits on it is because Dobby casts a shadow on it.
Corrected entry: You can see the wig line of Lucious Malfoy right before he steps into Hagrid's house, when they are coming to take Hagrid away.
Correction: Lucius Malfoy's hair is actually a white weave into the actor's naturally dark hair color (not a wig) and can be seen through the entire movie. A light weave into dark hair is the hardest to cover up.
Corrected entry: In the scene where Harry falls out of the flying car, you can see several items on the dashboard. None of the item move at all. They just stay glued to the spot.
Correction: It could be that Mr. Weasley used a sticking charm on those items so that they wouldn't move around if the car made a sharp turn or something.
Corrected entry: In the scene when Harry is in the memory of Tom Riddle, he has got a shadow. But in fact, he isn't "really" in that place, it is just a memory.
Correction: Only Harry himself, and the audience, can see it. Using the same logic we shouldn't have been able to see him. If he isn't there to block light how can he be there to reflect it.
Corrected entry: When Fawkes flew to Ginny and Harry after Harry told Ginny to follow the chamber out, notice that the dead basilisk is not there anymore. However, in the next scene, it reappears. (02:16:47)
Correction: The Basilisk lies dead in the water with its head on the stone floor the entire time. The Basilisk head is to the right of the huge head statue and the snake can be seen behind Harry when the shot faces him.
Corrected entry: At the end, Harry tells Dumbledore that he asked the Sorting Hat to be in Gryffindor, but he didn't: he asked not to be in Slytherin.
Correction: We can go back and watch the first movie any time we want, so Harry might not remember his Sorting as well as we do. It was two years ago and he only experienced it once.
Corrected entry: As Harry's being chased by the rogue bludger, Ron says 'I'll stop it' and as Hermione says 'no, its too risky, you could hit Harry' the boy behind her mouthes her words.
Correction: No he doesn't, he simply opens his mouth, it looks like to lick his lips.
Corrected entry: When Colin Creevey first takes a picture of Harry, right after the flash, look at the students behind Harry. Colin then introduces himself. Look behind Harry again - there are different and more students.
Corrected entry: Hermione says they will violate about 50 school rules by making Polyjuice Potion. When it turns her into a cat/human, she has to go to the infirmary and later Harry and Ron say she will be fine in a few days. Didn't she at least get detention for doing something so against the rules? I would think Hermione getting detention would be big news considering her goody goody brainy reputation.
Correction: Her embarrassing predicament might well be considered punishment enough. Plus there's not necessarily any evidence she was trying to make polyjuice potion - it could have been some sort of permitted animal transformation spell.
Corrected entry: When the Weasleys rescued Harry from Privet Drive, it showed him taking his trunk, and owl. The broom was not in his room, or packed in the car. Later when the boys arrived at school, the car ejected its contents before leaving the Hogwart's grounds, the broom was still missing. But Harry had the broom when he was playing Quittich. Seems doubtful he left his personal property at school over the summer.
Correction: The broom was in his trunk. As we find out in book 3, Harry's Firebolt was kept locked in his trunk before the Gryffindor/Slytherin Quidditch match for safety, therefore the trunks must be large enough to contain a broomstick.
Corrected entry: In the scene where Harry is in the hospital trying to regrow the bones in his arm, he hears someone coming and jumps on the bed. However, in the next scene, he is covered with the blanket, even though he did not move or change position.
Correction: When Harry jumps on the bed, he grabs the blanket and starts pulling it over him. In the cut to the next shot he would have had enough time to pull it up a bit more, and it never completely covers him.
Corrected entry: In the game of Quidditch, the bludger is smashing through all of the solid oak beams around the stadium, but when it hits Harry it only breaks his arm. Surely it should have smashed all his bones in his chest and arms with the speed it's going at.
Correction: No because remember, Dobby is controlling the Bludger, he just wants Harry to leave Hogwarts, not be severely injured or killed.
Corrected entry: At the end of the movie when Hagrid comes back, the camera starts going up and you can see that Hagrid is the same height as other teachers standing near doors.
Correction: Filch is the only person standing near the doors. In all shots showing Filch Hagrid is obviously much taller. Also, all of the teachers are seated at the front of the Great Hall.
Corrected entry: During the quidditch match, the first goal we see is scored by Slytherin. When they score, ALL the players come together and fly about in some sort of arrow formation. Wouldn't it have been VERY easy for the Gryffindor team to take the quaffle and score as there's no defense whatsoever?
Correction: In virtually every sport I've ever seen, once a goal is scored the game is stopped until the ball/puck/etc. is put back into play.
Corrected entry: After Errol delivers the Howler to Ron, he flies very close to Hermione's head, the wire attached to the Owl is visible as it passes her hair. It looked like it actually hits her in the face.
Correction: No wires are visible as I watch it. In fact, the actor playing Colin Creevey next to Hermione and if there was a wire attached to it that would be able to hit her hair, it would have hit him first. But it doesn't. And there is not wire visible, anyway. Not a mistake.
Corrected entry: In Defence Against the Dark Arts class when the Cornish pixies are destroying the classroom, Lockhart asks Harry, Ron and Hermione to nip all the pixies back in their cage. Hermione uses 'Immobulus' then the shot goes behind Hermione and you can see Neville on the ceiling. One pixie floats towards Hermione and part of it just vanishes. Poor computer animation?
Correction: I thought this too at first, but look more closely. The pixie actually floats to Hermione's front. It starts at her side, and moves in, passing by her stomach, so her back and cloak hide it as it moves by.
Corrected entry: At the end of year feast, Hermione runs up to Harry and hugs him then shakes Ron's hand. Then she sits down and her back is facing Ron and Harry's backs. Wouldn't that mean she sat down at the wrong table?
Corrected entry: In the scene where young Voldemort is telling Harry that Ginny was the one writing it on the wall, but where does she get the blood from? I doubt they just had buckets of blood lying around, and it would have taken quite a bit of blood, since she wrote 2 long, and big messages.
Correction: When Harry discovers the piece of paper in Hermione's hand in the hospital wing and he reads it, he says that the Basilisk fears the cry of the rooster. Ginny kills Hagrids's roosters so the Basilisk will stay at Hogwarts. Ginny used the blood from the roosters to write the message.
Corrected entry: When Harry Potter is writing in Tom Riddle's journal, Tom replies "No, but I will show you." The pages start to flip and stop on a blank page. A date then appears in the top right hand corner of the right hand side page as June 13th. Wouldn't all of the students have been at home that day 50 years ago? Isn't June 13th considered summer holiday? (01:29:17)
Correction: No. Hogwarts is in Great Britain, where the Summer Holidays are roughly from mid-July to mid-September.
Correction: On the contrary, his mouth does match the words if he was rolling his "r" in the word "vera-" as I suspect.
