Continuity mistake: As the boys are sitting and eating at the Weasley kitchen table and then joined by Mr. Weasley, in every wide shot Ron sits a good distance away from the table, yet in the close-ups, he's tucked right up against the kitchen table. (Visible in DVD fullscreen format) (00:12:10)
Continuity mistake: When Oliver Wood argues with Flint about who has the pitch for Quidditch practice, there is a close-up of Wood and the ties on his robe. When Ron is on the ground spitting up slugs, in the close-up of Colin, Wood's robe is seen clearly and the ties on his robe are actually put through the grommets and tied very differently, as is the case with others. (00:38:30 - 00:39:35)
Continuity mistake: In the scene where Harry and Ron are in the Dark Forest getting away from the spiders, the car comes and Fang gets in twice. First Fang goes in through Harry's door as the camera faces Harry, then Ron gets in the car and then Fang gets in again through Harry's door as Harry casts his spell. (01:48:00)
Continuity mistake: When it shows Harry writing in the diary, he writes "My name is Harry Potter." When he does this he says what he is writing. It shows what he is writing until he gets to the letters "Po..." Then the shot cuts out to Harry still continuing his sentence. But he only write about 1 or 2 more letters. That means he couldn't have finished his name. (01:28:10)
Audio problem: While Harry and Hagrid walk down Diagon Alley, as this shot opens Hermione runs toward Harry and just as Harry comes into view he is mouthing his line to Hermione, yet his voice is not heard, only Hermione's voice is heard. (00:17:25)
Revealing mistake: When Harry takes floo powder, in the wide shot Mrs. Weasley grips the pot with her right hand outstretched, her thumb at the top and the other fingers below, but in the next close-up of the pot, the pot is held by both of her hands around the pot. In the close-up of Mrs. Weasley holding the pot, the hands are not Julie Walters' (Mrs. Weasley) hands. (00:14:45)
Revealing mistake: In the scene where Harry Potter is writing in Tom Riddle's diary, we see Harry dipping his feather pen into the ink jar. Notice the shape and size of Harry's hand. When Harry actually starts to write in the diary we see a close up of Harry's hand, but it's not his actual hand doing the writing. The "stunt" hand has longer thinner fingers than Harry Potter's 12 year old hand. (01:28:05)
Continuity mistake: At the Weasley kitchen table, Percy hands the Hogwarts letters to each of the twins. A few shots later, you see one of the twins again being handed the same letter, this time from a different angle.
Continuity mistake: When Harry and Ron are reversing out of the forest to escape the pursuing spiders, Ron spins the car 180 degrees. However, when the shot cuts to inside the car both of them are leaning the wrong way. (01:49:20)
Continuity mistake: When the spider has Ron by the neck, Harry motions for Ron to move his head so he can take aim at the spider and yells, "Arania Exumai!" As the spider is forced away, in the close-up the back of Ron's head is positioned out his window. In the wide shot of the spider as it 'flies' away, Ron is sitting normally in the car. Yet, in the next close-up Ron's head is still positioned out of his window. (01:48:40)
Continuity mistake: When Hermione shouts, "Immobulus!" at the Cornish pixies, in the shot facing Neville, Harry, who's sitting on his knees, is right next to Hermione with Ron at his other side also on his knees. In the next wide shot, Harry and Ron, still on their knees, are much further away from Hermione. (00:37:40)
Continuity mistake: The distance between Harry and Ron when they're sliding into the Chamber of Secrets keeps changing. Harry jumps first, and Ron jumps a few seconds later, so there should be a little distance between them. But when they're sliding down, Ron is directly behind Harry. At the bottom though, Harry slides onto the ground a few seconds before Ron, meaning they're again some distance apart. (02:00:10)
Continuity mistake: In the Gryffindor common room, as Harry is preoccupied with the diary, there is a lantern and two stacked books right in front of him. In some shots the lantern is closer to him and in other shots the two books are closer. (01:28:25)
Continuity mistake: In the scene where McGonagall explains about the Chamber of Secrets there is a close up of Harry, and she obviously walks past him as you see her green robes block him from view for a second. However, the next shot shows her from the front walking towards the camera and you can see her walking past Malfoy, Crabbe and Goyle who are sitting behind Harry. (00:48:10)
Continuity mistake: At the Quidditch match, in the overhead close-up of Harry when he lands, the area of sand around him is visible. When Harry lifts up the Snitch and smiles, and in the next overhead shot as he begins to roll out of the way of the Bludger, the sand is still visible around his head. The tracks in the sand are different in each of these shots, but it's not been touched yet. (00:57:25)
Revealing mistake: The appearance of Harry's scar differs in some close-ups. For example, at the Quidditch match, in Harry's first close-up his scar has an outline and is thicker than other shots. Other examples are, in Harry's first close-up as he flies behind Malfoy below the pitch stands and also when he reaches for the Snitch after his arm breaks. (00:53:35 - 00:55:50)
Continuity mistake: In alternating shots while Harry is in the Chamber of Secrets, he has a pimple above his lip; in other shots he does not. (02:06:40 - 02:11:30)
Continuity mistake: When Harry first encounters Dobby, as he walks toward the corner of the bed to bow to Harry, a single sock and other clothes are lying on the bed. In the next shot facing Harry, the sock and clothes on the bed have noticeably changed positions and the two long ends of the Gryffindor scarf that hang over the trunk is visible. When Dobby sobs, as he walks off the bed, only one short end of the Gryffindor scarf hangs over the trunk, and it also changes position in following shots. (00:03:10)
Continuity mistake: The smudges on Harry's face and the dirt on Harry's cloak, pants, etc., change in consecutive shots, throughout the shots after the rock slide, within the Chamber of Secrets and thereafter. (02:04:00)
Continuity mistake: While Harry looks through the seemingly empty diary, in the first overhead shot, the quill lies semi diagonally on the table at the top right corner of the diary. In the next shot it lies right next to Harry's right hand. (01:27:20)
Chosen answer: After Harry hands it to Lucius, Lucius hands it to Dobby to carry. After Dobby is freed by the hidden sock and protects Harry from Lucius, Lucius leaves it behind.
