Harry Potter and the Half-Blood Prince

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".


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.


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.


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.


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.


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.


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.

Super Grover Premium member

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.


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?


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.

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.


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

Corrected entry: When Ron, Hermione & Harry are sitting in the Great Hall discussing Ron's break-up with Lavendar, there is one row of tables behind Harry - one row behind Ron & Hermione - total, 3 rows of tables. When Harry leaves the Hall, there are 4 rows of tables as there should be.

Correction: Have another look, because there are actually two tables behind Harry, not one. Seated at the table directly behind Harry are Marcus Belby, Dean Thomas and Cormac McLaggen chatting it up, and behind that table is the fourth table with Lavender.

Corrected entry: Professor McGonagall tells Harry that Slughorn will accept students who had Exceeds Expectations on their N.E.W.T. The exams that Harry took the previous year were called O.W.L., while NEWTs are the exams 7th year students take.

Correction: Have another listen. Harry says, "I was told I had to get an Outstanding in my O.W.L." Professor McGonagall responds, "So you did, when Professor Snape was teaching Potions. However, Professor Slughorn is perfectly happy to accept N.E.W.T. students with Exceeds Expectations." This means Slughorn's Advanced Potions class is for N.E.W.T. level students. There is no mistake.

Corrected entry: [SPOILER WARNING] After Dumbledore finishes drinking the potion in the cave, it is Harry who takes the horcrux from the basin and puts it in his pocket. However, when Harry approaches Dumbledore's dead body, the very same locket had seemingly fallen out of Dumbledore's pocket and Harry takes it again. Actually, it should be in his pocket already.

Correction: There was plenty of time for Harry to have given the locket to Dumbledore, at any time during their boat ride out of the magically enhanced cave, offscreen, just after Dumbledore parted the flames with the spell, until they actually apparated once outside the cave's entrance.

Corrected entry: Before Dumbledore takes Harry by side-along apparition to see Slughorn, he tells Harry to hold his left arm because his right hand is all shriveled up. When they apparate away from Slughorn's house to the Burrow, Harry grabs Dumbledore's right (i.e. the wrong) arm.


Correction: First off, there is no "wrong" arm. Dumbledore still has use of his right arm/hand despite the poison, as seen on a few occasions, including when Harry takes hold of Dumbledore's right forearm as they Apparate from the Astronomy Tower to the cave's location and also when Dumbledore holds his wand with his right hand within the cave. Secondly, both when going to and leaving Budleigh Babberton, Harry takes hold of Dumbledore's left forearm for the Side-Along Apparition.

Corrected entry: At the start of the movie Ginny has dark brown/black hair, then in the next shot shes gone back to ginger.

Correction: After multiple viewings of the film, Ginny's hair is never seen to be brown/black. It is always ginger. Her hair may have seemed darker due to the lighting.

Corrected entry: In the scene where Draco Malfoy attacks Dumbledore, Bellatrix Lestrange walks in wearing dark lipstick. The camera switches to a side view of Draco, and Bellatrix kisses him on the back of the head, and she is wearing no lipstick. The Camera goes to Dumbledore, then back to Draco and Bellatrix, and her lipstick has reappeared.


Correction: Bellatrix is always wearing lipstick. From a front camera angle, her lipstick appears dark. When her face is seen in profile, a bright light source shining directly on her face highlights her features, including her lips, making them only appear lighter, but we still see its shine.

Corrected entry: At the end of Order of the Phoenix, Harry is going home with all his friends. However, at the start of Half-Blood Prince, they show the Daily Prophet at the Ministry taking pictures of Harry and Dumbledore.

Correction: The last scene in The Order of the Phoenix happened AFTER the opening of The Half-Blood Prince. The first scene is a flashback to the events at the Ministry.

Brad Premium member

Corrected entry: When Harry opens the potions book the first time, it says, "This book belongs to the Half Blood Prince" with blood underlined 3 times. When Ginny opens it, it says, "This book is property of the Half Blood Prince."


Correction: First, when Harry first opens the book the writing reads "...is property of...", and not "...belongs to...". Second, when Ginny opens the book and says aloud "This book is property of the Half Blood Prince" we are not actually shown the writing that she reads. Third, Harry first opens the book and reads it at the front cover and Ginny opens to the back cover.

Corrected entry: When the necklace is brought to McGonagall, Hermione is to the left, then Ron, then Harry. When Snape arrives and inspects the necklace, Hermione is now in the middle. When the shot shows them again, Hermione is again on the far left side.

Correction: You need to have another look. Ron stands between Hermione and Harry the entire time, from the moment McGonagall thanks Leanne.

Corrected entry: During the Death Eater attack, Mrs. Weasley reaches out to stop Harry before he actually runs away.


Correction: Harry quickly rushes past Mr. and Mrs. Weasley and just as he momentarily stops in front of them Mrs. Weasley shouts and protectively reaches her arm out to him, then he runs after Bellatrix as she shouts, "No!" There is no problem with how that is played out.

Super Grover Premium member

Corrected entry: At the welcoming feast, Dumbledore mentions Tom Riddle, and the name causes all of the students to start talking. Very few, if any, of the students should know what Voldemort's real name was.


Correction: Voldemort's public return at the Ministry of Magic happened before school let out. Between then and the start of the new term, during which Harry's been dubbed as the 'Chosen One', it is really not inconceivable that a number of the students would have come to know Voldemort's real name (within the film's world) and then whispered it to others who didn't know.

Corrected entry: In the Christmas scene at the Burrows, while Mr. Weasley talks to Harry alone, he is sitting behind an old muggle stereo that suddenly disappears.


Correction: In the shed, when Mr. Weasley takes a seat the record player is lying in front of him on some other stuff. As he and Harry speak, each time the shot faces Mr. Weasley the camera pans in towards him, closer and closer, over the record player. With each shot of him, less and less of the record player is seen at the bottom of the screen, and in the next to last shot of Mr. Weasley we can still see a bit of it at the bottom. So by the last shot of Mr Weasley the camera is right up in front of him and the record player is simply not seen.

Corrected entry: When Harry is giving Dumbledore the poison to drink, Harry takes a cup of poison (with a little left in the bowl). Harry approaches Dumbledore saying, "This is the last one you need to drink". Harry then goes back to the bowl and the remaining poison's suddenly gone, leaving the necklace fully exposed.


Correction: There is an entire basin filled with the liquid potion and we are shown Harry filling up the small shell cup only a few times, so there is much time that passes offscreen between these shots for Harry to have emptied the basin completely, just before he tells Dumbledore that it is the last of the potion.

Corrected entry: During Aragog's funeral, Hagrid says he had him since he was an egg. In Chamber of Secrets Aragog says he came to Hagrid in the pocket of a traveler. Aragog had already hatched when he found Hagrid.

Correction: In the film 'Chamber of Secrets' Arogog tells Harry and Ron that he "came to Hagrid from a distant land in the pocket of a traveler" - he did not say that he was already hatched, so we must presume he was STILL an egg. (In the book Arogog actually states "A traveler gave me to Hagrid when I was an egg.")

Super Grover Premium member

Corrected entry: When Harry first gets the old Book of Potions, he opens the front cover and sees the name Half Blood Prince. Later when Ginny pulls the book from him and reads the name to Hermione, she has opened the back cover and is reading the name from there. Later on Harry is again looking at the book, and once again the name Half Blood Prince is at the front of the book.


Correction: It's entirely possible that the name is on both the front and back cover. Students often write their name in more than one place on text books.

raywest Premium member

Corrected entry: It had been mentioned in the previous films that no one can apparate to or from Hogwarts. Yet, near the end, we see Dumbledore (with Harry along) apparating from the top of astronomy tower.


Correction: Harry asks, specifically, about this very thing, and Dumbledore explains that he has certain privileges available to him, among them, the ability to apparate in and out of Hogwarts as he pleases.

Corrected entry: At the Great Hall feast where Dumbledore is addressing the students, he says Tom Riddle's name. Before he said that, there was a shot of the table that Harry and his friends were sitting at. Directly after Dumbledore says Tom Riddle's name, it goes back to the table, but Harry isn't sitting there anymore.

Correction: He's still there. You can see his hand. He's just hidden by Ginny. He's looking around her back which places him right behind her from the camera's POV.

Corrected entry: If it wasn't for the contract that Emma Watson (Hermione Granger) signed to complete the last few movies, the Half-Blood Prince and to-be Deathly Hallows (to be made in to two movies) would not have happened. However, despite the success of the contract, Watson has revealed that she will no longer be acting after the last installment of Harry Potter.

Correction: Without quoting a source, it's impossible to say for sure that the final three movies "would not have happened". Even though Watson is now identified with the character, it cannot be said for sure that the studio would not have recast the part. The franchise is too profitable.

Hermione Granger: She's only interested in you because she thinks you're the Chosen One.
Harry Potter: But I AM the Chosen One.



In the dormitory, when lovestruck Ron is going gaga over Romilda, he is wearing a brown sleeveless tee shirt and its tan trim has many holes. When Harry brings Ron to Slughorn, Ron is still wearing that tee shirt, but now some of the holes are gone and the rest of the holes have changed position.



Young Tom Riddle is played by newcomer Hero Fiennes-Tiffin, who is the nephew of Ralph Fiennes, the actor who plays Lord Voldemort, aka Tom Riddle.
