Continuity mistake: When Harry goes to his detention, Umbridge places the spoon on the saucer. When she gives Harry the quill, the spoon has changed position. (00:36:45)
Continuity mistake: During Harry's first detention, before he starts writing and while Umbridge is still talking, he's sitting at the desk. He's holding the quill in his right hand, and his left hand and arm are resting on the desk. The shot switches to another angle, and his left arm is immediately off the desk. Umbridge is still talking, so there is no time lapse between the two shots. (00:37:10)
Continuity mistake: In Umbridge's office, Harry begins to write "I must not tell lies" on the paper and in the next close-up the writing on the paper differs. The paper itself moves on the pink mat, note the flowers in relation to the text. (00:37:45)
Continuity mistake: In the Gryffindor Common Room, when Hermione and Ron sit down beside Harry in the first shot, Hermione's left shirt ribbon hangs over her shoulder under her hair. When it cuts to the front shot, as she sees Harry's hand, that ribbon hangs properly down the front of her shirt. (00:39:10)
Continuity mistake: When Hermione asks if Ron ever stops eating, she has her hand up to her face. Camera cuts to behind Harry who has just walked over to them and her hand is no longer at her face. (00:43:20)
Continuity mistake: When Dolores has Sybil Trelawney in the courtyard, sending her from Hogwarts, Dolores says, "Actually, I can," and then holds up a scroll. The way and direction she holds the scroll changes between shots. (00:47:25)
Continuity mistake: When Dolores has Sybil Trelawney out in the courtyard, Sybil's suitcase in front of her is horizontal to us, even when she bumps into it, it remains horizontal. After Professor McGonagall comes over though, the suitcase is now diagonally positioned. (00:47:35)
Continuity mistake: When Dumbledore has had a stand off against Umbridge regarding Sybill Trelawny, he turns to go back into the castle. When he does, there is a huge group of kids around him. When it cuts to a shot from the front, a huge gap has appeared in the kids instantly. (00:48:35)
Continuity mistake: When Ron says, "Who are you and what have you done with Hermione Granger", his head is cocked to the side a little, but in the next shot, his head is facing forwards. (00:54:35)
Continuity mistake: In the Room of Requirement, before the Christmas holiday, Harry compliments the DA on a job well done, and they clap. There are two consecutive shots of the group from different angles, and between shots Cho's wand turns upside down and another girl's wand changes hands, etc. (01:01:25)
Continuity mistake: As the students are departing the Room of Requirement and all thanking Harry, the group of students around Harry completely changes between shots. It's especially noticeable as the boy with shoulder-length brown hair passes Harry twice. (01:01:55)
Continuity mistake: When Arthur Weasely is attacked by the snake, his wand keeps moving its position. First it's on the floor near him, then it is closer to his body, then he is holding it. (01:05:25)
Continuity mistake: When Harry wakes up after dreaming about Mr. Weasley's attack, you can see stubble on his neck. However, when he is in Dumbledore's office and later in Snape's, his face is clean shaven. (01:05:30)
Continuity mistake: When Harry is being tested by Snape on being able to block his mind from being read, the sweat stain on his jumper (sweater) changes from larger to smaller during the scene. (01:07:00)
Continuity mistake: At the Order's headquarters, after the 'bandaged' Mr. Weasley's return and the gifts are handed out and they are toasting Harry, the positions of things on the table differ between shots. (01:08:30 - 01:09:35)
Continuity mistake: After Harry's vision of Arthur Weasley's attack, he has the first Occlumency lesson with Snape. The windows behind Harry have a diamond shape pattern, with horizontal and vertical divisions on the glass. In the last shot, as Snape orders Harry to focus, when the camera dramatically pans out through these windows there is only a diamond shape pattern on the glass. (01:09:45 - 01:10:50)
Continuity mistake: During Mr. Weasley's celebrated arrival at 12 Grimmauld Place, in the wideshots facing that end of the table something tall is placed right beside the wood hutch, off to Ginny's left. In the shots facing the doorway, including when Harry joins them, there is nothing beside that hutch. (01:11:15)
Continuity mistake: After bandaged Arthur arrives at Grimmauld Place, in the shot facing the twins, Molly hands the twin on the left the gift with blue wrapping and the twin on the right gets the orange wrapping. Next shot facing Arthur, as Molly pulls her hands away from the gifts, each twin actually has the opposite color than the previous shot and it is at this point they switch gifts onscreen. (01:11:35)
Continuity mistake: At 12 Grimmauld Place, when Harry and Sirius are in the room with the Black family tree, as Sirius says, "My parents with their pure-blood mania," the area of the wall with both Sirius's and Andromeda's names and burned off pictures is quite visible (as in other shots as well). Bellatrix's name is beside Andromeda's (her sister), but there is no picture over Bellatrix's name banner in this shot (only branches and leaves), nor in any other shot, except in the previous close-up, as Sirius says, "My deranged cousin," where there is a picture of Bellatrix over her name. (01:13:25)
Continuity mistake: In the Room of Requirement, when Neville and Harry are alone, Neville stands before the mirror and Cedric's photo and other things are taped to the mirror. Not only does the position of the photo, etc, change between shots, the tape also differs. This occurs in other scenes as well. (01:17:40)
Answer: Draco is shocked because a teacher is never allowed to hit a student, not for any reason. He never expected Umbridge to behave in such a manner.
