Corrected entry: When Harry is preparing a new Quidditch team, and after Ginny shouts for everyone to shut up, there is a man walking behind the goal posts in the background. Normally this could be just any other character, but the man is wearing regular trousers and a long shirt or jacket.

Correction: Everyone is wearing normal clothing. It could easily be another student.

Greg Dwyer

Corrected entry: At the top of the Astronomy tower when Dumbledore is talking to Harry about the Horcruxes, as Harry walks towards Dumbledore you can see two people, either crew or extras, walk behind the "wall" to the right of the shot.

Correction: When Harry's talking to Dumbledore while the Headmaster is being mawkish, note the tall cabinet with two large glass doors behind Harry. When Dumbledore starts describing their journey's dangerous destination, as Harry is walking toward the railing it is actually Harry's mirrored reflections (two separate reflections), which can be seen (walking just like Harry) on each of those two large glass doors at the right side of the screen. Dumbledore's faint moving reflection can be seen a bit as well. (Having the DVD player settings set on bright helped confirm the correction).

Corrected entry: When Snape appears after Harry has used Sectum Sempra during his fight with Draco in the bathroom. Harry leaves the bathroom and there is an extra or a crew member standing against the wall.

Correction: That's a student (note the school robe) waiting at the doorway/wall who can be seen twice, first when Snape walks in and when Harry walks out.

Corrected entry: When Tom Riddle is talking to Professor Slughorn about horcruxes, Slughorn mentions that you have to kill to make a horcrux as it rips the soul apart. Tom Riddle says, "Can you only split the soul once, for instance seven?" This shows that Tom was planning to make seven horcruxes, however he only intentionally created six horcruxes and as Dumbledore said in 'Deathly Hallows Pt 2', "You were the horcrux Voldemort never intended to make, Harry". Surely Tom would have said six horcruxes then, not seven.

Professor Lazarus

Correction: Sorry, but this incorrect, and the film has muddled it a bit. Riddle's (Voldemort) intent was to split his soul into seven pieces by making six horcruxes "in addition" to the soul piece left inside his body. He believed that "7" was the most magical number. Harry became an accidental horcrux, which then made seven horcruxes in all, plus the soul shard that was left in Voldemort. That made eight soul fragments total, but only Dumbledore, and later Snape, knew about the one inside Harry. It was only before his final confrontation with Voldemort that Harry learned he carried a horcrux. Voldemort never knew about the horcrux inside Harry.

Corrected entry: When Harry gets the Advanced Potions Making book, "This Book is the Property of the Half-Blood Prince" is on the first page. A little later when Hermione and Ginny want Harry to turn the book in, Ginny grabs the book from Harry and looks at the last page and reads "This Book is the Property of the Half-Blood Prince".

McClimber

Correction: I don't see why this is a mistake. The Half-Blood Prince couldn't have labeled the first and last page of his old book?

Grumpy Scot

Corrected entry: In the ending scene (astronomy tower); It's a high windy place, you can hear the sound effect of the wind. But when Hermione opens the pendant with the piece of paper, it doesn't fly away.

einat162

Correction: Wind behaves strangely as it eddies around architecture. Even our real-world, relatively streamlined buildings have peculiar wind currents swirling around the upper floors. It's not unlikely at all that the paper wouldn't have been caught in a gust.

Corrected entry: In Diagon Alley, Hermione says, "Oh no, everyone got their wands from Ollivanders!" Hermione should have noticed Ollivanders destroyed when they entered the Alley as you have to walk past Ollivanders to get to Weasley Wizard Wheezes.

TheMrSnape

Correction: Depends on how they got there. If they used the Floo network to get to Diagon Alley from the Weasleys' house (which they've been shown to do before), we don't know where in the alley they'd arrive. Given the family relationship, they may well have used the Floo network to go straight to Weasleys' Wizard Wheezes and thus would not have seen Ollivanders.

Corrected entry: When the Death Eaters attack Diagon Alley, Lucius Malfoy is walking when he's supposed to be in Azkaban.

TheMrSnape

Correction: No, he isn't, nor is there anybody who appears to particularly resemble him. The closest is one individual briefly seen from behind who has long white hair, but this is hardly something unique to Malfoy.

Corrected entry: When Harry and Ron talk in the bedroom, Harry is watching Draco where he goes with the special map of Hogwarts, the name of Draco on the map is misspelled Malpoy.

Correction: No, it most certainly does not. The style of the font used for the all-capitalized "MALFOY" has a decorative flourish at the end of all the letters' (except "O") lines. The "F" you're seeing may seem like a "P" to you, but it is truly an "F".

Corrected entry: Harry and Dumbledore apparate from the tube (train station) at few minutes after 11 p.m. (as evidenced by the date that Harry made with the waitress for when her shift ends at 11). However, they apparate to the town where Prof. Slughorn is hiding and the grandfather clocks reads approximately 10:26 p.m.

MovieFan612

Correction: The grandfather clock is simply wrong, and there are actually at least two reasons that can be: One, Slughorn has faked an assault by the death eaters on the house, and in the process of creating that chaos, the clock might have been harmed. Or two, and even simpler, Slughorn states the owners of the house are away on holiday, so the clock has stopped, because it wasn't wound up regularly.

Ioreth

Corrected entry: In the scene where Draco attacks Harry on the Hogwart's Express, it appears that they shot to scene at both ends of the train compartment and then spliced the different takes together. If you watch the numbers on the wall above the seats, they bounce back and forth from low to high numbers.

Correction: There is nothing unusual about the seats' numerical order. Seat numbers 1 and 2 are to the left of the door (for which Draco pulls down the shade, and also Luna walks through) and numbers 3 and 4 are to its right, with the numbers increased in each row, so 5-8 are facing 1-4 with the tables between. Draco, who sits farther back facing that door, sits at seat number 14, with 13 to his left, seats 15 and 16 to his right across the aisle, and across the table are Pansy and Blaise in seats 9 and 10, facing Draco. The numbers are perfectly consistent.

Corrected entry: After Draco is escorted out of Slughorn's party by Snape, and Harry begins to spy on them, you can see crew rugs used to quiet Draco and Snape's footsteps. The same rugs are visible earlier in the film when Harry and Ron walk down a corridor after Slughorn's class.

Correction: There is no rug in the corridor when Harry and Ron head toward Slughorn's Potions class (not "after"), and there is no rug in the corridor when Snape pushes Draco up against the wall, while Harry overhears them.

Corrected entry: When Dumbledore rises to give a speech, the gold owl on his pedestal shakes its head and then spreads its wings, which are perfectly clean. Later during the speech, the wings are shown covered in dried wax from the candles.

Correction: When the owl spreads its wings at the start of Dumbledore's statements, the wings are below the candles, so as the headmaster continues to speak, the melted wax drips down to the wing tips. Absolutely no mistake here.

Corrected entry: When Harry drinks the Felix Felicis, he appears to drink/down the entire bottle, but the next shot shows that it is still half full. They may have shot both versions because in the book Harry only drinks half and saves the rest for later.

Correction: When Harry starts to drink the Felix Felicis we see some of the liquid emptying, but the fact is we are UNABLE to see whether or not the vial has actually been emptied in this overhead shot. In the next shot facing Harry, we see the vial is half empty. There is no mistake since we cannot determine the amount of liquid that is left in the vial in the first overhead shot.

Corrected entry: When the students and teachers raise their wands in salute of Dumbledore, Hagrid is holding a wand like everyone else. He should be holding his pink umbrella, containing the pieces of his wand, which was snapped 54 years previously.

Correction: Hagrid is not holding anything, his hands are down the entire time.

Corrected entry: When Harry Potter is stunned by Malfoy and covered in the invisibility cloak, Luna Lovegood is able to remove it with a spell. However, it has been stated that this cloak, being one of the three hallows, cannot be summoned or moved by magic.

Correction: In the movie series, nothing has been mentioned yet about what the Deathly Hallows are. It is only in the books that the cloak is said to be unresponsive to magical spells. The film makers have artistic license to make small plot changes.

Corrected entry: When Dumbledore has died, and Harry is kneeling next to him, you can see Dumbledore breathe. I don't think even if he's a wizard that he can breathe when he's dead.

LBA1403

Correction: When I first saw the movie, it also seemed to me that he was breathing. However, when I saw it again, I noticed that the movement of Harry's hands in Dumbledore's chest give the impression that Dumbledore is breathing - but he's not. Harry's hands move Dumbledore's clothes on his chest, not his breathing.

Corrected entry: When Harry and Dumbledore go into the house where Prof. Slughorn is staying in the beginning of the movie, dragon blood drips onto Harry's head. Dumbledore touches it, but there is blood still left on Harry's head. Once Slughorn is revealed he assesses Harry, but Harry's hair is different and the blood stain is no longer on his forehead.

Correction: There are moments where Harry is offscreen, and that is sufficient time for him to simply wipe away the dot of blood with his left hand/arm, which would also change the bit of the hair at his forehead.

Corrected entry: When Harry uses the instant darkness powder on the Hogwarts Express so that he can spy on Draco, it is daytime. When everyone clears off the train when they arrive it is night outside. Hermione says "Wheres Harry?". But there must have been at least an hour between when Harry left them and Hermione asks. Why is she only asking where he his now?

AshleyWeasley

Correction: When Harry leaves their cabin, he says, "I need some air," and she and Ron see him take his Invisibility Cloak off the rack. They know Harry wants time to himself so they leave it be. When the train arrives at Hogsmeade Station, she asks, "Where's Harry," BECAUSE the train arrived, since all students are to disembark, and Ron tells her he's probably already on the platform. During the time Hermione and Ron are offscreen (while Harry is eavesdropping), for all we know Hermione could have voiced some concern about Harry's whereabouts and Ron, being Ron, would have said Harry was fine on the train.

Super Grover Premium member

Corrected entry: Near the beginning of the film, where Harry is in the train station with Dumbledore, they are talking and Dumbledore lifts his left hand which is severely burnt. Nearer the end of the film when Harry and Dumbledore find out about the Horcrux's, Dumbledore brings out from his drawer a book from the second film and a ring belonging to Tom Riddle's mother. He explains that it was difficult to get the ring, and then holds up his burnt hand, but this time it's his right hand that is severely burnt, not his left.

Katie..x

Correction: It is ALWAYS Dumbledore's right hand that exhibits the blackened sign of being poisoned, not burned.
