Immediately after Katie is cursed by the necklace, Harry, Ron and Hermione are in Mcgonagall's office talking about what they saw in Hogsmeade. Harry says, "It was Malfoy." As both teachers turn Mcgonagall says,"That is a very serious accusation, Potter."As she says this, she looks oddly transparent. You can see the window pane design through her robes, particularly in the shoulder. This continues to be true until she says "I suggest you go back to your dormitories." This could possibly signify a green or blue screen behind them. [She's not transparent. It's a trick of the camera. A glare from the bright window behind her. You notice you can't see the vertical slats of the windowpane. Only the horizontal. That's because the glare is carrying across her body horizontally and where the horizontal slats are there's no light to cause a glare.]

In the film Harry Potter and the Half Blood Prince, Professor Slughorn (during one of the 'Slugclub' meetings) asks Hermione what her parents do for a living, she replies, 'They're Dentists.' Slughorn and the other wizards stare blankly, not knowing what Dentists are. However, in the film 'Harry Potter and the Chamber of Secrets' in the burrow, we see the magical clock that shows the family's whereabouts, and we see that there is a section marked 'Dentist'. [The Weasleys are much more muggle-friendly than most wizarding families. And that clock is such a rarity that even Dumbledore is impressed by it. Perfectly logical that some few members of wizarding world would know what a dentist is, especially the Weasleys, while most do not.]

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". [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?]

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. [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.]

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. [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.]

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

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. [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".]

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. [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.]

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. [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.]

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. [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.]

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. [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.]

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. [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.]

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. [Hagrid is not holding anything, his hands are down the entire time.]

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. [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.]

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. [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.]

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. [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.]

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? [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.]

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

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. [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.]

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. [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.]
