Visible crew/equipment: When Hermione and Harry go back in time, they duck and hide from Malfoy (after being punched) and his friends as they leave. The bulging rectangular outline of the transmitter (for hidden cordless mic) is visible at her lower back, under her pink jacket. It is visible in a few shots, including when they are at the pumpkin patch. The outline of Harry's transmitter is visible at his back, as he bows to Buckbeak at the pumpkin patch, when they rescue him. (01:45:10)
Revealing mistake: When Fred rushes in to fight the Black Knight Ghost in Mr. Wickles' castle, he is hit in the face several times with the back of his shield. As he falls, you can see the pad on the back of the shield to protect his face. (It is not noticeable when he first runs in.) (00:23:20)
Revealing mistake: In the first scene of the film, Evan is writing frantically in a journal and his last words that the camera zooms in on are "Save her". Look closely and you can see that those same words are already indented on the page as indicated by a visible letter "s" and "h" and a period that had already been written on the pad of paper. Obviously they had done some other takes. (00:01:35)
Continuity mistake: When Puss in Boots plants his sword in the ground then jumps out of his boots, his sword, boots and hat are nowhere near any trees or grass. Yet after attacking Shrek, Puss in Boots lands in his boots, and his boots, sword and hat have moved to being right beside a tree. (00:32:30)
Visible crew/equipment: As the camera moves in on the bull that is about to be grabbed by the vampire, if you look under the bull, you can see two men hiding behind it. You can see their legs. They are probably there to keep the bull standing still. When it cuts they are gone. (00:26:05)
Continuity mistake: In the scene where Count Olaf starts walking from the balcony to the stairs, you can see his right hand when he is saying "lovely home" with no writing. Later when he looks at his hand to remember Violet's name, his hand has writing on it. (00:09:20)
Continuity mistake: When Jenna first walks around after turning 30, the camera pans around the apartment and we get a good view of the small glass table in the lounge, and there is a remote control next to a magazine. When Jenna goes and sits on the yellow chair though, the remote is now on the magazine. Later when Jenna is throwing her letters, the remote has moved to its original place. (00:13:30 - 00:14:45)
Continuity mistake: When Bobbi, Roger, and Jo break into Sarah's house, just as they hear the noises upstairs Roger's arms change from at his sides to crossed. (00:33:25)
Continuity mistake: When Hellboy is walking at one point, holding his gun up in his left, gloved hand (just after one of the agents has said "This place is like swiss cheese"), watch the frame. It switches suddenly so his right hand (the stone one) is his left, and he's holding the gun in his "right." (00:59:40)
Revealing mistake: In the Arena Challenge scene, the statue of Toa Lhikan falls on the herd of Vahki and part of the statue's mask is going through the ground. (00:22:30)
