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.) (01:29:40)
Revealing mistake: When Dumbledore is dueling with Voldemort in the Ministry Atrium, there is a close-up shot of Voldemort as he opens his mouth wide, laughing. The filling in the Dark Lord's upper molar is visible in his newly acquired body. (01:54:25)
Revealing mistake: In the Department of Mysteries, when Lucius removes his mask Bellatrix stands behind him, but her entire body has been digitally blackened. Additionally, there are two distinct shots in which there is a digital shape highlighting Bellatrix's face/upper body that moves as she moves. The first occurs when she remarks, "He knows how to play," then after Lucius begins to say, "Prophecies can only be retrieved," when he continues with the words, "by those about whom" it occurs once again in the close-up. (01:44:25)
Revealing mistake: When the students are riding on the Thestrals to London, in one shot Luna's hair is practically still. Seeing as they're flying fast in the air, and the Thestrals' wings are flapping strongly, surely her hair would be blowing much more fiercely. (01:41:15)
Revealing mistake: When Harry is going down to Hagrid's hut and discovers he isn't home, he looks over the forest discovering the thestrals. The camera moves back so Harry is also visible in the shot, but as he becomes visible, just shortly at his head to the left some of his head goes missing showing that it is a chroma-keyed background / blue or green screen. (00:40:50)
Revealing mistake: Throughout parts of the film, there are points where it is obvious that Harry doesn't have glass in his glasses. One of the more noticeable points is when he is talking to Sirius in the fire. (00:50:00)
Revealing mistake: Just as Dumbledore is about to introduce Umbridge the shot cuts to Umbridge. Look at the candle to the right of Snape; you can see a string holding on the right hand side of the candle holding it up. You can also see the strings on all three of the candles.
Answer: When Voldemort originally attacked Harry, he was acting on information provided to him by Snape. But Snape's information was not complete, ergo why Voldemort lost his powers. He wants the prophecy in order to hear it in its entirety, because he believes it will give him the information he needs to kill Harry.
