Best Harry Potter movie mistake pictures of all time
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.)
Revealing mistake: In the Forbidden Forest, HRH are introduced to Grawp. Just as the giant lifts Hermione off the ground, in the shot from behind her, Hermione's legs disappear below her calves; the digital lines are actually visible. Slow-mo is not necessary. (Only visible on fullscreen DVD.)
Continuity mistake: At the Ministry of Magic, as Yaxley is reprimanding Ron, who is disguised as Reg Cattermole, the initial on Yaxley's Ministry tie pin changes direction. In one shot, the letter "M" is tilted to the left, and in a subsequent shot, it's slanted in the opposite direction.
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 rectangular outline of a power pack (battery pack 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 power pack at his back is visible as well, as he bows to Buckbeak at the pumpkin patch, when they rescue him.
