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. (Time)

Visible crew/equipment: In the dueling scene, when Snape pulls Malfoy back onto his feet, a cameraman is visible on the far left of the screen. (Time)

Continuity: When Lockhart falls down the hole into the Chamber of Secrets, we hear him hit the ground a second or two later. When Ron and Harry jump down, not only do they take longer to get down, they also slide down the pipe, rather than fall straight down. (Time)

Revealing: In the Quidditch scene, Harry breaks his right arm and cradles it on his chest, but when he is laying on the ground after he falls off his broom, he then leans directly on it when he sits up to get away from the Bludger. In the shot immediately afterward, he has his hand cradled in front of him again. (Time)

Continuity: When Myrtle is flooding the girls' bathroom, the tap that later doesn't work (the entrance to the Chamber) is happily churning out water - it's on the side nearest the door, so we see it clearly both times. (Time)

Revealing: During the car flight (on the way to Hogwarts) Harry and Ron are have gone out of control outside Hogwarts. During the scene when the car is approaching the whomping willow the car is massively out of proportion compared to when the car is in the tree. (Time)

Visible crew/equipment: After the car spits them out and the car drives away and they are chasing after it, if you watch closely you can see the shadow of someone driving the car. (Time)

Continuity: When Harry arrives at the Weasley's we see the clock that shows where everyone is. We see the twins' and Ron's picture moving to show they're home, but no-one else's picture is in the same place. Shortly afterwards we see that everyone else is already home, except Mr. Weasley. (Time)

Visible crew/equipment: Rushing to make Hogwarts Express at the train station, the shot opens as the camera pans Ginny's trunk and TWO marks come into view. While Ginny and Mr. Weasley push her trolley, Mr. Weasley (Mark Williams) is cued and begins to say, "10:58, come on, come on!" just as the actor hits his tape MARK on the ground below, while Percy's (Chris Rankin) trolley hits its tape mark, so Harry is visible behind him, and cues Mr. Weasley to continue speaking. In the shot when Mrs. Weasley says, "Okay" for Ginny to go and in the shot as Harry says, "Let's go," their marks are obviously gone. (Visible on DVD fullscreen.) (Time) Submitted by Rikki

Visible crew/equipment: When in the Whomping Willow, Ron asks, "What's happening?" and Harry replies, "I don't know." After a few other shots, in the next two front close-ups of the boys as they scream, Harry, Ron and Hedwig are not alone in the car. A crew member's HAND is quite visible holding the bottom of Hedwig's cage and in the 2nd close-up is actually laying the cage on its side!! (Visible on DVD fullscreen.) (Time) Submitted by Rikki

Visible crew/equipment: In Flourish and Blotts, when Lockhart says "Which, incidentally, is currently celebrating its 27th week atop the Daily Prophet bestseller list," the overhead camera pans up. As the camera passes his feet, Tom Felton's (Draco Malfoy) mark, two long strips of white tape are perfectly visible on the balcony floor where he stands. (Time) Submitted by Rikki

Revealing: When Harry is fighting the Basilisk on top of the skull in the Chamber of Secrets, you can see that there is a safety tip on the end of the sword. (Time)

Continuity: In the scene where Harry, Ron, and Hermione are drinking the Polyjuice Potion, Harry leans toward the mirror and starts to gag or something. You can clearly see his shirt is half-unbuttoned. Then they cut away to another shot farther back. Then they cut back to him, and his shirt is buttoned up, nice and neat. (Time)

Continuity: When Ron and Harry are escaping from the spiders in the flying car the passenger's side window that broke earlier hitting the Whomping Willow is not broken, you can see Ron's reflection. A minute later you see that the window is broken again. (Time)

Visible crew/equipment: While Harry is chased by the Bludger, Hermione says, "No! Even with a proper wand you could hit Harry..." Three shots later, as Harry passes the blue Ravenclaw tower, the back of his robe flies up and the metal base of the SEAT he sits on is perfectly visible. Some shots are filmed vertically, as he sits on the attached seat with the upright broomstick in front of him, but then edited with the background plate to look as if he is lying on the horizontal broomstick. Hence the need for a seat perpendicular to the broomstick. (Time) Submitted by Rikki

Continuity: In Moaning Myrtle's bathroom, the mirrors don't reflect at all, they're very dirty. But when Harry changes into Goyle, his face is clearly reflected in one of the mirrors. (Time)

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. (Time)

Revealing: As Harry climbs the Salazar Slytherine stone head's locks of hair, the Basilisk crashes his face and creates the first immense hole. As Harry tries to climb higher, it pounds into the stone again creating another huge hole, higher up on another lock of hair, to Harry's left as he hangs on. However, when the Basilisk smashes his face into the stone a third time, as Harry nears the top, the second huge hole is GONE, in this shot and in the first wide shot in which Tom Riddle is visible. (Time) Submitted by Rikki

Revealing: Harry and Ron's trunks are being thrown out of the car and in the shot just before Harry's close-up, Ron's trunk (the other trunk says HP) slams down on the grass. The top of this trunk has a large perfectly symmetrical hole in the center with four round marks around it, which was probably involved in the throwing somehow. In the wide shot as Hedwig is being tossed out, the trunks are clearly visible and there is no hole in either, nor is there a hole in Ron's trunk at any other time. (Time) Submitted by Rikki

Visible crew/equipment: Just arriving at Diagon Alley Hagrid says, "I was looking for Flesh-Eating Slug Repellent. They're ruining all the school cabbages." In the next shot Hermione exits the shop and runs towards Harry. On the ground is Dan Radcliffe's (Harry) red mark, which he promptly steps on just before Emma Watson (Hermoine) glances down and steps on her own black tape mark. (Visible on fullscreen DVD.)
