Continuity mistake: There are two scenes during which Harry is shown having visions of the Dept of Mysteries while he is asleep. The first scene occurs after Harry's confrontation with Seamus in the Gryffindor common room. There are shots of Harry lying in bed wearing a short sleeve, crew neck tee shirt, but when he is startled awake by the vision of Voldemort, he sits up wearing a buttoned henley tee. The next day is the first day of Defence Against the Dark Arts class with Umbridge. That last shot of Harry in the henley tee shirt was cut from a later scene. Later in the film, when Harry has the vision of Arthur Weasley's attack, he is wearing the henley tee shirt. (00:34:00 - 01:09:35)

Continuity mistake: Once the chipmunks are inside the food cupboards, they begin to devour everything inside. Theodore is seen chewing off a corner of a box of Lucky Charms cereal and eating the cereal that pours from the hole.

Continuity mistake: When Joe gets injured and he insists the back-up quarterback goes in, he takes his wristband with all the plays on it off, so it can be given to the back-up.

Continuity mistake: First day in class, when Hoager "beeps" at Jesse, Mrs. Myers writes two words. The word "verb" is over the word "subject" on the board, in the close-up. After she turns around, in the following shots, the word "predicate" appears, disappears, then reappears and "subject" is written over "verb" now. Additionally, during this scene, all the other writing on the blackboard changes between shots as well. (00:06:15)
Continuity mistake: During the dinner where she first meets Mrs. Coulter, Lyra's drink changes color from deep red to a reddish orange between shots.
Continuity mistake: When Remy and Emile are cooking the mushroom on the roof, notice that the mushroom is skewered on the antenna. When Remy and Emile are hit by lightning and sent careening off the roof, the mushroom is instantly on a stick in Remy's hand, instead of the antenna. It could've been sent flying by the lightning bolt, but even if it was, there was no stick in the previous shot for it to have ended up on. (00:07:50)
Continuity mistake: Right before the final race, there is a wide shot of all the surfers. In that shot, Cody has his Big Z necklace that he chucked earlier.

Continuity mistake: During the scene where Lewis is first on the roof-top, and Mildred comes up to speak with him, the box he is sitting next to is plain wood on one side, and tallied on the other.
