Corrected entry: When Harry and Hermione watched their past selves from the wood, there were some scenes where events happened too fast in second scenario. They see Lupin say "Immobilis" and the Whomping Willow stops moving, then just a few seconds later they see Snape coming. But the first time, Snape arrives in the Shrieking Shack few minutes after Lupin. Also Lupin transforming into a werewolf is too short in the second scenario. Hermione howls a few seconds after he changes, but the first time, Lupin transforms, then he fights with Sirius for about a minute.Feather
Corrected entry: In the scene where Snape takes over the Defense against the dark arts class, (about werewolves) when the projector changes slides, on the screen the image moves clockwise at the top. However, when you see the projector, the light enabling a picture to be projected is on the bottom and the slides rotate counter clockwise.kevkevtheman
Corrected entry: In the very beginning, Harry is performing the Lumos spell in his bedroom. He's underage, therefore he should be well aware that he's breaking the secrecy rule and should have been alerted to the Ministry, yet they only take notice of him when he 'blows up' his aunt.HulkObsessedChick
Corrected entry: Hermione says that Harry wouldn't want to run into himself in the past, that he'll go mad. There have most likely been many instances when something like that would happen, a polyjuice user encountering the sample, for instance. It would probably cause confusion, but it's very unlikely that someone would go insane as a result.Knever
Corrected entry: When Peter Pettigrew is seen on the Marauder's Map, his dot's footprints are displayed as that of a human's even though he is in his rat form. However, during the credits Sirius' dot is shown changing from human footprints to dog pawprints and back again. Either Peter's prints should've shown up as rat prints or Sirius' should have consistently been shown as human prints.
Corrected entry: Platform Nine and Three Quarters is supposed to be a secret platform that only magical people can access. However when Harry, Ron and Hermione have boarded the train and are looking for a cabin we can see out of the window a GNER (Great North-Eastern Railway) train visible on the next platform. The train is most noticeable for its blue colour with a single red stripe running the length of the train.Scrappy
Corrected entry: When the Dementors are boarding the train, everything starts to go cold, so much so that the water on the windows starts to freeze, and even more noticeably the water in the bottle completely freezes. Once the Dementors have gone, the windows are completely free from ice and the water in the bottle has melted again. This is not possible in the short space of time that passed.Scrappy
Corrected entry: At the Leaky Cauldron a guy picks up a bottle and wraps a rag around it. A second later the bottle is gone.
Corrected entry: When the Hogwarts Express stops and Ron turns to look out the window, Hermione says "Ouch Ron, that was my foot". However, in the next shot, Ron's feet are nowhere near Hermione's. He would have had to have been leaning in order to reach her foot, and he's sitting up pretty straight, too fast for it to change in one shot.
Corrected entry: When the entire school is banqueting after their arrival, D. Malfoy says: "Potter. Is it true you fainted. I mean you actually fainted?" In the book, he found out because Neville was in the compartment as well, and he told "nearly everyone." But, in the film, only Harry, Hermione, Ron, and Professor Lupin are in the compartment. The three friends wouldn't have told them, and a schoolteacher doesn't go around telling such things to students. So, as Harry himself asked, how did Malfoy find out?
Corrected entry: When the Knight Bus slows down before the two double-deckers, you can see them and the other traffic around it slow down noticeably as well. The other vehicles also speed up when the Knight Bus does.
Corrected entry: When Dumbledore is studying the slashes on the portrait of the Fat Lady, you can see, especially well when the light shines on it, that the actual paining is extremely smooth. But a real paining would have at least some trace of paint brush strokes.
Corrected entry: When Neville has the Boggart explained to him, he switches positions between shots.
Corrected entry: In the beginning when the Dursley's are sitting at the dinner table and Mr. Dursley says "Can I tempt you, Marge?" you will notice that there is a spoon in the pudding bowl. The very next shot you will notice the spoon is missing from the bowl and the reappears in the next shot.
Corrected entry: When Harry, Ron and Hermione are going to Hagrid's hut before Buckbeak's execution they walk past McNair, the executioner, sharpening his blade in the courtyard. Harry and Hermione run through the courtyard again after going back in time and they pass right by McNair for a second time. Just prior to this Hermione told Harry they "must not be seen".
Corrected entry: In the Great Hall, the teachers all sit up at the top table. However, in the long shots, the filmmakers use quite a few doubles for the more popular characters (e.g. Prof. McGonagall and Hagrid), because they would cost too much if they used the proper actors.
Corrected entry: In the beginning when he is casting the Lumos Maxima spell, he is doing magic outside of school, which is not allowed.
Corrected entry: In the scene near the beginning where Harry leaves the Dursley residence and sits on the street to rest (before the Knight Bus arrives and the dog appears), you can see the condensation in his breath. That would only happen if it was very cold, which in this case is not since it's the middle of the summer at that time.
Corrected entry: During the Dementor's entrance into the train carriage, everything freezes. Because the frost effect is digital, the water level of the glass on the window sill does not change when it freezes. It should have risen as the ice grew in mass.
Corrected entry: Before Hagrid's lesson, during the scene where Draco Malfoy and his friends are teasing Harry about the Dementors, Draco pulls his hood/hat onto his head, but it doesn't have a good grasp and starts to slip off; the front of his hair is visible. A split second later from a different camera, the hood is snug on his head and no hair can be seen.
Corrected entry: After Professor Lupin confiscated the Marauder's Map from Harry Potter, Harry told Lupin that he saw Peter Pettigrew's name on the map. Although both Lupin and Potter did have their own knowledge about Pettigrew, Lupin was his friend and Potter learned from overhearing the conversation between Professor McGonagall, Madame Rosmerta and Cornelius Fudge, there was no indication that they ever had any conversation about Peter Pettigrew. Lupin's reaction to Harry's revelation was rather odd because he looked worried instead of surprised that Potter already had some information about Pettigrew. Potter himself also seemed really familiar with the name rather than showing any indication of curiosity about Pettigrew. Such a profound discovery should have made him question Lupin about the nature of the finding rather than just walking away from his office.
Corrected entry: When Professor Snape caught Harry missing the curfew, Professor Lupin came to intervene and save Harry from being punished. Lupin also took a parchment, the Marauder's Map, before Snape could confiscate it and asked Harry to come to his office. In his office Lupin mentioned to Harry that the map was a weapon for Sirius Black but he never asked Harry what is hidden inside the parchment nor did Harry ever mention a word about the map. Obviously Lupin should have had no knowledge about the Marauder's Map if he have never even heard anything about it.
Corrected entry: When Harry firsts receives the Marauder's Map and says "Is that...?" and one of the twins answers "Dumbledore in his study...", the shot shows us Dumbledore's footsteps. But the name above the steps say 'Albvs Dumbledore' rather than 'Albus Dumbledore' or 'Albvs Dvmbledore'.s.ounder
Corrected entry: In the scene where Harry says goodbye to Remus Lupin they are standing on opposite sides of the desk. There are huge piles of books to the right side (viewer's right) of the desk. When the shot jumps closer the books should obscure part of the view but in fact the books are on the floor behind the desk and the desk is nearly empty.
Corrected entry: Right after Hermione gets angry and punches Malfoy, Malfoy and his goons run off. As he is running away, Draco Malfoy calls out to his fellow Slytherins "Not a word to anyone." When Harry and Hermione relive the scene again, Draco runs off saying "Not a word to anyone, understood?."PoPEyE
Corrected entry: In the scene when the Knight Bus turns and drives on the bridge, you can see the London Eye in the background. This part of the movie was set in 1993, but the London Eye was built in 1999.
Corrected entry: When Harry is wearing the invisibility cloak, he has to open the doors to the candy store and the bar when going in and out. However, when he is outside walking with Hermoine and Ron and near the shrieking shack throwing snowballs at Malfoy, none of the falling snow is accumulating on his head. If he can't walk through things when he is invisible, shouldn't the snow be landing on his head giving away the fact that he is there?
Corrected entry: When Harry sneaks into town and comes out of the candy shop, all you see is a floating lollipop going through the crowd, while the rest of him is covered by the Invisibility Cloak. The entire stick is visible. If Harry is holding the stick through the cloak, then part of the stick should be missing/hidden too.
Corrected entry: When Harry and Hermione go back in time and are crouching outside Hagrid's hut, before Hermione throws the stone, you hear the other Hermione in the hut saying 'I meant me'. In the original scene, filmed in the hut, Hermione says this and then the stone immediately comes through the window and smashes the pot. However when they go back in time, there is at least a 6 second pause from when the other Hermione says it and the stone smashes the pot.
Corrected entry: The Knight Bus comes to a halt just short of an elderly person who is crossing the street. Through the bus's window the crystal chandelier can be seen swinging, due to the sudden stop, from side to side. But it ought to swing front to back, owing to its previous motion.
Corrected entry: In the Hospital Wing scene near the end of the film (when Harry and Hermione go back in time after protesting Sirius' innocence) Dumbledore finally closes the doors after the Hogwarts clock chimes seven times. The clock then carries on to chime roughly the right number of times for being apparently 10:30pm (11 times before Harry and Hermione go back in time). In the later scene, when Harry and Hermione have just seen Sirius leave, they run up to the Hospital Wing, as Dumbledore closes the doors after the eighth chime, not the seventh as before. The clock then carries on chiming through the rest of the scene until it strikes 13.
Corrected entry: When Harry and Hermione have travelled back in time, she tells him that they mustn't intervene with anything as terrible things happen to witches and wizards who meddle with time (they think they've gone mad). During the whole experience, they are both very careful not to be seen. Yet as they are rescuing the hippograff, after going back in time, surely the past Harry, Ron, and Hermione would have seen the future Harry and Hermione rescuing the hippograff from the top of the hill they were standing on?.
Corrected entry: Throughout the final night of Aunt Marge's stay, Aunt Marge (on her chair) keep switching positions.
Corrected entry: While Aunt Marge is at the table, the glass breaks in her hand and in the next few shots the pieces of the glass are gone.
Corrected entry: In the scene in Hagrid's hut when Harry, Ron and Hermione are leaving we can hear Cornelius Fudge say "the Hippogriff known as Buckbeak is to be executed at sundown." However they exit to execute him not even five minutes later, no where near sun down as the sun is visible in the sky.
Corrected entry: When Aunt Marge has been blown up and is floating out into the garden, Vernon grabs a hold of her hands. From the shot looking at Vernon, Marge's cuffs on her jacket are very wide and loose around her wrist - but in the next shot of Vernon looking at Marge the cuffs are tight around her wrist.
Corrected entry: In the scene where they (the Griffindors) go to the fat lady the first time she opens inward, then the shot changes to look like it was in the common room, and the fat lady's portrait is now open outward.
Corrected entry: When Harry goes over to Buckbeak, he pulls the chain and it comes through the ring so easily, that it looks like it isn't connected. This is probably to make it easy for Harry to free Buckbeak, but it means that Buckbeak could have flown away on his own, when he was supposed to be secure.
Corrected entry: In the scene when all the kids are leaving for Hogsmeade, you can see that Harry's face is pressed against the inside of the big clock tower overlooking the entrance to Hogwarts. Later on in the movie, when Harry and Hermione are back in time, the camera zooms through the same clock and you can see that the back is covered by lots of equipment. How did Harry have his face pressed against the glass?
Corrected entry: When Buckbeak "attacks" Draco, he scratches him on the left arm, but in the next scene in the Great Hall, it is Draco's right arm that is bandaged.
Corrected entry: When Peter has been changed back into a human he holds up his hands and there are definitely ten fingers. In the next shot there is a finger missing on his left hand but during the rest of the scene it alters all the time.
Corrected entry: In the Shrieking Shack confrontation, the Disarming Charm is used several times. Isn't it odd how the effect of 'Expeliarmus' has lessened from the explosive body-throwing of the second movie to barely plunking wands to the ground in the third?
Corrected entry: After Harry faces the boggart which changed into a dementor during the Defense Against the Dark Arts class, Lupin tells the class to go. Harry still stares at the spot where the boggart was. If you look closely you can tell the shot was reversed for Harry's scar is on the wrong side of his forehead.sdgirl98
Corrected entry: At the end of the film when Harry is in Lupin's office, just after Lupin has said Harry can have his map back, he folds it up on the table. Then Lupin leaves the office, as Harry turns to watch him walk down the stairs, you can see the table over Harry's shoulder, but the map has disappeared and Harry did not pick it up.
Corrected entry: After Sirius has flown away on Buckbeak, the clock bell begins to toll, altogether there are 14 tolls. Even in the magic world there isn't a 14 o'clock. And since the time turner goes back in hours (stated in the book) it should be three hours on from 7.30pm, making it 10.30, and don't most clocks strike on the hour?
Corrected entry: When Harry is attacking Malfoy, Crabbe and Goyle near the Shrieking Shack while under the invisibility cloak, Harry moves very rapidly, as he attacks two people at the same time. They couldn't possibly have been hit by Harry as he was swinging one of them around by the scarf. Also he is far away from this action and no contact is seen to have happened.Graeme Chicken
Corrected entry: Professor Lupin tells Harry that he recognised him the first time he saw him because he had his mother's eyes (and didn't have to be told who he was). The first time Lupin saw Harry, Harry had passed out and his eyes were shut - and Hermione was using Harry's name before he came round.
Corrected entry: In the last shot of the choir, near the end of the trailer, a girl in the second row, to the right of the screen, can be seen looking directly at the camera.
