Corrected entry: When Ron and the Weasley twins come and rescue Harry from the Dursleys, Harry asks 'What are you all doing here,' to which Ron replies 'Rescuing you of course.' During these lines, the twin in the back of the car mouthes his lines.
Corrected entry: When the hand grabs Harry in Knockturn Alley, you can see that one of the CGI fingers goes THROUGH Harry's hand.
Correction: The Hand of Glory used in the film, seen in Borgin & Burkes, in the theatrical release and in the deleted scenes, is a mechanical hand, whose wires are hidden underneath the pillow and shelf it sits upon and controlled off screen. Nevertheless, I still looked frame by frame and at no point do any of the Hand of Glory fingers 'go through' Harry's hand.
Corrected entry: After Harry uses floo powder, before Mrs. Weasley says "What did he say, dear?" You can see crew members' shadows moving around on the wall to the left of the window.
Correction: The moving shadows we see on the wall are the rest of the Weasleys trying to get a better look into the fireplace. They could not be crew members' shadows because the Weasleys are in front of the wall the whole time.
Corrected entry: In the scene where Errol crashes into the window, ducks are visible outside. They are obviously a painted set prop, because they don't move at all.
Correction: They are not a painted set prop because they move. When we first see Errol, one of the ducks moves its head, then we see the Weasleys and then Errol again (smash into the window) and now the ducks are in a different position than they were before and moving their necks/heads.
Corrected entry: When Dobby visits Harry in the hospital, he bashes himself on the head with the bottle of Skele-Gro. Before disappearing, he puts the bottle down on the table at the foot of the bed. After he disappears and the shot changes, the bottle is back in its original place on the side-table at the head of the bed; the table at the foot of the bed is empty. (01:01:50)
Correction: Whether viewed in the widescreen or fullscreen DVD, the Skele-Gro is not on the table beside the bed, when Harry is back in bed, while they bring Colin in and only PART (the right side) of the rolling table at the foot of the bed is actually visible in that shot.
Corrected entry: When the Whomping Willow hits the windshield, just after the car falls to the ground the glass cracks, but it barely hits it. (00:27:45)
Correction: No glass cracks after they fall from the Whomping Willow. When the car falls out of the Whomping Willow and hits the ground below, Ron lays on the gas and pulls away just quick enough as the Whomping Willow slams a huge part of itself onto the GROUND, so it does NOT touch the car as it speeds away. All the severe damage to the car's glass windows is done while still UP in the tree, where it is perfectly visible as it happens.
Corrected entry: At the very start, when Harry is looking through the book Hagrid gave him in the previous film, Hedwig's cage is on the table beside him. In the Dobby scene, it's gone. When Ron comes to rescue Harry, it's there again. (00:01:10 - 00:05:15)
Correction: During the 'Dobby scene' Hedwig's cage is NOT gone. Hedwig's cage is on top of the dresser beside a lamp, in the same place as the earlier shots and where it always is. The cage can be seen 1) when Harry closes the bedroom door as he sees Dobby on his bed, 2) when Harry apologizes for supposedly offending Dobby, 3) when Dobby bangs his head and yells, "Bad Dobby!" the first time.
Corrected entry: When Harry, Ron & Hermione are discussing the chamber, after Harry says 'But if there really is a chamber of secrets and it really has been opened,' you can see Malfoy, Crabbe & Goyle are just about to pass the group. Then it changes angles and Hermione says 'the heir of Slytherin has returned to Hogwarts...' and it goes back to the wider angle and they're right behind them again.
Correction: There is nothing wrong with the walking continuity of Malfoy, Crabbe and Goyle behind Harry, Ron and Hermione. In the first wide shot of the entire hallway Malfoy et al are just walking closer, but STILL way behind when it cuts to a quick shot of Hermione. As the next close-up of Ron opens, Ron begins to speak as Malfoy is coming closer, then Malfoy et al pass Ron on his right.
Corrected entry: During the Herbology lesson, Malfoy's earmuff flaps change size.
Correction: No, they don't. The very SAME oval earmuffs are visibly on his head in the four shots of Malfoy wearing earmuffs. The only thing that changes, which is still perfectly consistent, is that the headband starts off in the first shot at the top of his head, but in the subsequent shots has slid down to the back of his head, so because the earmuffs are oval in shape, they are now turned a bit on his ears. But, like I said already, it still remains consistent, there is no mistake here.
Corrected entry: When Harry enters the Weasley house, there are five bowls stacked on top of each other, next to the sink. When they take the food from the table, there are, at most, only four bowls stacked together.
Corrected entry: When Harry gets into the Weasley car escaping from the Dursley's, Ron is in the front of the car. When they fly off, he is in the back.
Correction: Harry passes Hedwig's cage to Ron who STANDS at the SIDE of the front seat and Ron passes the owl to one of the twins in the back seat. While the camera faces Vernon slamming open the door, yelling, "Petunia, he's escaping!," Ron simply slides to the back. So in the next shot, from behind Vernon, as Harry is on the bedroom's window ledge, Ron sits in the back seat.
Corrected entry: Before Ron's Howler arrives, he puts down the wand he was fixing. In the next few shots, the wand is there but the roll of tape he used to fix it with is gone.
Correction: The roll of tape is perfectly visible at the bottom corner of the screen next to the wand, near the green apple, as the Howler gives Ron the huge raspberry and begins to shred itself. (DVD fullscreen)
Corrected entry: After drinking the polyjuice potion, Ron and Hermione both dive into cubicles - all the doors are open before they go in. Harry then changes while looking in the mirror, but when we see the stall doors again, three are closed. (01:19:45 - 01:20:50)
Correction: The first cubicle door is closed the entire time. When Hermione says, "Cheers," the closed door is visible between Ron and Harry. Ron runs into the second cubicle and Hermione runs into the third - which is Moaning Myrtle's cubicle, hence three doors shut. (Interesting fact to note - that first cubicle door is also closed behind Ron when Hermione brews the potion while she sits on the floor.)
Corrected entry: In the very beginning of the movie, Harry is looking through a photo album. He turns to a picture of him, Ron, and Hermione. Hermione's hair is different in this movie than in the first. In the photo, Hermione's hair is like it is in the second movie, but the picture was supposed to have been taken during the course of the first movie, in which her hair was a bit different. (00:01:05)
Correction: Pictures can change their hairstyles; note Lockhart's pictures.
Corrected entry: In the scene with the Rogue Bludger, Harry and Malfoy dive to the bottom of the stands to chase the golden snitch, they have to go through all the wood. But in the first movie, there is just sand there, as we see when Angelina Johnson gets knocked into the stands and falls. (00:55:45)
Correction: This is not a mistake in the film, but a difference between the first two movies. The Quidditch pitch could have been renovated during summer break, it's as simple as that.
Corrected entry: In the scene where Lockhart is saying something about the Bandon Banshee, he calls it a "him." Banshees are female spirits.
Correction: Don't forget Lockhart is an idiot and lies about all his adventures. This shows that not only is he a liar, but he didn't even bother checking his facts.
Corrected entry: Harry Potter is the Seeker for the Gryffindor Quidditch team; his sole responsibility is to get the Golden Snitch. When we first open the Quidditch scene the camera focuses on the Chasers throwing and intercepting the Quaffle around the field. When one of the Slytherin Chasers has the Quaffle, Harry is speeding right behind him and continues to pursue him as he swerves around the audience stands and other players until he stops and we see the close-up of him. Why is he pursuing a Chaser when he should be looking for the Snitch? (00:53:35)
Corrected entry: In the dueling scene, Gilderoy Lockhart says, "I said disarm only." Harry and Malfoy seem to wait for his line to be over instead of performing another spell on each other. Why would they care what he said? (01:07:50)
Correction: Eh, because he is the teacher?
Corrected entry: Myrtle points to the sink where she saw the eyes of the basilisk, but she points to a different sink than the one that is the entrance to the Chamber of Secrets.
Correction: According to Myrtle she died when she heard some voices so she opened the closet door. During that time the basilisk could move to that spot, it's less than 2 meters away from the entrance.
Corrected entry: When Harry takes a handful of the floo powder we can see the top level of the powder is flat and undisturbed. It should be disturbed, as only moments before the shot Ron took a handful. (00:14:20)
Correction: It is MAGICAL floo powder. It can transport people from one place to another. You don't think it could flatten itself?
Correction: No, the twin in the back does NOT mouth Ron's line.
