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.) (02:04:40)
Continuity mistake: As Sy is developing Nina Yokin's birthday party negative the film canister shown has the green and white Fuji colors and layout. When Sy holds the processed negatives up to the light to view the exposures the film information along the side of the strip indicates the film is Kodak Portra 400VC. (00:06:50)
Continuity mistake: During the scene where the police first go to arrest Howard and John is deciding which door is the right one his plastic face plate is down and in the next shot it is clearly up. (00:10:55)
Revealing mistake: When Jason climbs onto the rail of the fire escape, it is not attached to the wall - intentionally, it has not broken - but then in another shot, two seconds later, it 'breaks'. It pulls out of a visible hole in the wall, although it was never actually attached and there was no hole before. (00:23:25)
Revealing mistake: When Becky meets Simon in the cube, they hug, then Simon literally stabs Becky in the back. As she falls down to the floor, her black shirt reveals not only some of her chest, but part of a black microphone wire. (01:15:15)
Continuity mistake: Bret shoots himself under the chin and a hole is blown in his forehead. Moments later when he's on the ground, for a split second, you can see his forehead completely unblemished. (01:03:00)
Revealing mistake: When Fred smashes his arm through the round window of the garage and grabs Shaggy, if you look you can see some kind of clear tape on his arm to protect him from the glass. This is quite noticeable in closeups. (00:47:10)
Continuity mistake: When Alice and Adam get in the cab outside the bookshop, the number on the back of the taxi is 90167, there are no other markings on the back and the Y on the number plate has a long stalk. When they're pulling away from some traffic lights later, the number has changed to '14290', there are the words "fairaway 95" on the back and the 'Y' has a small stalk. Note that, since the number plate (K651EYW) stays the same, for at least one of the shots they were driving a car around London with the wrong plates on. (00:08:30 - 00:09:25)
Continuity mistake: Throughout the scene where Roland and Maud are sitting on the floor looking through the things in the box from Ash's grave, the head of Maud's hairclip switches constantly from one side of her head to the other.
