Continuity: As Ron and Harry watch in the background, Crabbe and Goyle hold cupcakes that change position, then start eating Hermione's cupcakes. When the close-up faces Crabbe, the little bit of cupcake in Goyle's hand is visible. However, when Goyle rolls his eyes up as he begins to fall backwards, the cupcake in his hand is nearly whole.

Continuity: Throughout the film, one of the young actors may have one or more pimples on their face, yet in the following shots which may take place only moments later, the pimples are gone, or visa versa. For example, when Hagrid joins Harry, Hermione and Ron outside when he overhears, "Mad and hairy...," Harry has one on his cheek. Neville tells them to rush to Harry's room. While Harry, whose own pimple has disappeared, searches the mess, the one on Ron's chin is visible, though it wasn't in the shot outside. Scenes are shot out of sequence, hence the erratic complexion continuity problem.

Visible crew/equipment: When Harry and Ron are under the invisibility cloak in Hagrid's hut, Hagrid, Dumbledore and Fudge are joined by Lucius Malfoy. In the wide shot as Malfoy steps in, all the mats - their marks - are visible under Malfoy, Fudge and Dumbledore. Then later Dumbledore says, "If the governors desire my removal, I will of course.." and in the shot facing Malfoy as he finishes, "..step aside," the mat that Malfoy now stands on is visible as is the blue mark behind his feet. It's also visible in an earlier shot after he announces the order of suspension. The mat at the foot of Hagrid's chair disappears as well. (Visible on fullscreen DVD.)

Visible crew/equipment: Ron and Harry hide under the invisibility cloak in Hagrid's hut. After Lucius Malfoy enters he starts to walk towards the invisible boys and they nervously back up. As they back up, something large comes up from the bottom of the screen in front of the boys then quickly goes back down. The boys do NOT hold anything when they go under the cloak and they do not hold anything when they come out. (Visible on fullscreen DVD.)

Continuity: As Aragog approaches Harry and Ron, Harry says, "Were friends of Hagrid's," and Harry carries the lantern palm side up, at his hip. Yet in the next shot, it's palm side down and the lantern handle is at his shoulder. In the next shot, though it's still at his shoulder it's palm side up now. Then in the two shots facing Aragog, the lantern is down low, but in between those two shots, in the shot facing Harry, his elbow is bent, the lantern is higher up and Fang stands further away.

Visible crew/equipment: When Harry and Ron are in the car fleeing from the spiders, there is a close-up of them looking towards the back of the car as they drive backwards. Two shots before the close-up of them yelling, "Wooooh!!!" there is a wide shot of the Dark Forest and the car at the top of the screen just as it starts to jump over the tree roots. In this wide shot at the bottom of the screen, the HEADS of TWO crew members are wonderfully visible! (Visible on fullscreen DVD.)

Visible crew/equipment: Ron and Harry discuss the Basilisk's victims and, speaking of Mrs. Norris, Harry says, "There was water on the floor that night. She only saw the Basilisk's reflection." Just before Harry reads aloud from the paper again, the crew's gas torch canister with regulator and tip, that sits in a bucket beside another bucket, leans against the wall. (Visible on DVD fullscreen.)

Continuity: In the scene where the Chamber finally opens, we first see Harry, Ron and Professor Lockhart from the front, and Harry and Ron are slightly behind Lockhart, and in a position to threaten and guard him. When you next see them a moment later from behind, Lockhart is behind them and they are in no position to guard him.

Visible crew/equipment: When Harry, Ron and Lockhart are in the girls' lavatory, Harry speaks Parseltongue to open the Chamber. Lockhart then tries to escape so the boys push him back. In this shot the white strips taped to the small black mat, which itself is taped to the floor for Rupert's mark, are plainly visible at his feet.

Visible crew/equipment: Upon entering the Chamber of Secrets, Harry spots Ginny and runs towards her. After the last close-up of Harry's face as he runs, there is shot that faces Ginny, showing Harry's back. At the very start of this shot, on the bottom left corner of the screen two overhead studio lights, other equipment and scaffolding are perfectly visible, reflected in the puddle to Harry's left. Later when he runs out of the pipe, towards Ginny, some light reflections are visible as well. (Visible on DVD fullscreen.)

Continuity: In the Chamber, when Harry runs from the Basilisk he ends up at a gated dead end, with steel bars that are embedded in a circular stone wall. When Harry crouches down, as the Basilisk's face nears, the manner in which the bars are embedded in the stone is actually quite different.

Visible crew/equipment: After Harry climbs up the side of Salazar Slytherine's stone head in the Chamber of Secrets, the first time the Basilisk slams his face into the stone in the wide shot, the bottom of a crew member's denim pant LEG and SHOE are totally visible lying on a work surface, beneath the stone head's beard! The digital editors overlooked this one. (Visible on fullscreen DVD.)

Revealing: In the scene where Harry is stabbing Tom Riddle's diary for the last time, he closes the book and we see a close up of its cover, covered in ink. In the next close-up of the diary its cover is clean, and a small blue dot (where the ink subsequently squirts from) is visible in the centre for Harry to aim the tooth at.

Continuity: There is a scene where Harry is talking to Ginny in the Chamber, and he is holding his arm right below the wound. In this shot Harry has blood on his hand. When Ginny notices the wound, Harry moves his hand up to cover the wound. Now his hand is spotless. In the very next shot, however, Harry has blood on his hand again.

Continuity: Dumbledore asks, "Why then did the Sorting Hat place you in Gryffindor?" and in this close-up the Sorting Hat sits on two books. In the next shot, as Harry answers, "Because I asked it to." The hat now sits on three books in this close-up. During this entire scene in Dumbledore's study, things including the Sorting Hat and lamp behind Dumbledore to his right, change position depending on camera angle.

Visible crew/equipment: While Harry is in Dumbledore's study, in the two semi-overhead shots as Lucius Malfoy says, "So it's true. You have returned," and later when he says, "Come Dobby, we're leaving," sitting on the floor directly behind Dumbledore is a large STEEL piece of the crew's equipment, plus in the second shot another piece of equipment actually moves in front of the steel piece.

Revealing: At the beginning of the scene near the end of the movie with Lucius Malfoy fuming at Dumbledore in his office, Malfoy's hair is fanned back behind his shoulders. The lighting in the room illuminates the back of his neck, where you can see his real, short brown hair.
